I was going to use the Limo bus service but it seems the earliest departure from NRT to the Conrad is at 13.55,as we arrive at 11.00 I don't want to hang around that long.On a previous visit we used the NRT express but were staying at the Four seasons Marunouchi so in easy walking distance.Is it best to take the NRT express and then a taxi,don't want to use the subway as we will have a couple of cases and bags ,any advise would be gratefully received.

N'EX to Tokyo station + taxi will work fine. The taxi will probably cost about 1300yen.

One cheapo option with minimal effort would be:
11.42am Keisei Limited Express - departs from Narita Airport Terminal 1
12.45pm Arrive Aoto
Change at Aoto (just walk across the platform IIRC)
12.48pm Keisei Oshiage Line - departs from Aoto
1.13pm Arrive Shinbashi station (Asakusa line)
Then a short walk to Conrad

Are Conrad guests interested in cheapo options?

Thanks jib71 NEX it is, didn't want to blow the drinks budget on a taxi from NRT

Is the Conrad the 1st or the last stop from NRT on the Limo bus?

It's the first pick-up on the rtn to NRT so I would assume it's the 3rd and last drop on the way from NRT.
Are there plenty of taxis at Tokyo City Air Terminal (has loads of limo bus departures from NRT) what would be the approx time and cost to the Conrad I really don't fancy the station stairs with the cases.

Does anyone go to TCAT any more even with all those busses? Guess so.

To go from the Narita Express at Tokyo station to the taxi level can be done entirely by taking 2 elevators (although the second one is a bit obscure, it's just outside the exit ticket gate you'll see first when you get off the train and to the left). Or entirely by taking 3 escalators as well, going up to the level where the local lines leave.

Bus to TCAT and then taxi is also very do-able.
I would guess approx. same total cost as N'EX + Taxi.

Advantages:
Bus allows you to avoid stairs (but there are elevators and escalators at NRT and Tokyo station). And the bus departures to TCAT are very frequent.

Disadvantages:
The bus trip takes longer than N'EX - especially if you hit traffic
(but the high frequency of buses can make up for that).
I don't like sitting on the bus - feel more comfortable in the train. (Yes, even in the crappy Bombardier coaches that they use on the N'EX these days - the original cars were so much better...)

So far I am scheduled to arrive NRT at 2100, which mean I'll probably miss the last NEX after picking up bags & customs as I see the last one is at 2140. Is there any other way to get to the Conrad other than taxi?
Thanks.

As mentioned you can take the Limobus to Tokyo Station or TCAT then taxi to the Conrad:

Last week I got in to late to catch the last Limo bus to the Conrad. I ended up taking it to the Imperial Hotel (3,000 yen) and then catching a taxi.

The fare from the Imperial hotel to the Conrad was about 900yen. My other option was to go to Tokyo station and take a taxi from there, but the hotel looked closer on the map.

Would the JR Sobu Line Rapid train to Shimbashi be a good option? Also, on the following route, there are no change of trains involved, right?: http://xs113.xs.to/xs113/07126/NRT-Shimbashi.gif

Is Conrad within a walkable distance from the Shimbashi station? If not, how much would a taxi ride cost?

How would the options compare to taking the Sobu Line to the Tokyo station + taxi to Conrad (which should be approx. 1200 JPY, right?)

Any advice would be appreciated

Yes, the Sobu train is direct, and you can walk to the Conrad from Shimbashi. It's about 5-10 minutes. The thing is that it's a bit hard to navigate in that area, and I believe you have to cross some foot bridges. The Sobu line platforms at Shimbashi are also basically in the seventh level of Hell, and you'll have to deal with steps etc. just to get out of the station. So if you go that route, have your heavy luggage delivered, and only take a small overnight bag with you.

If you're going to do that, it may be faster and just as cheap to take the Keisei Skyliner or limited express (whichever is departing first) to Nippori, then change to the southbound Yamanote Line, which also goes to Shimbashi.

If you'd rather keep your bags by your side, then the limousine bus is the best option, followed by taking NEX to Tokyo Station and a cab from there.

I second this option -- Nippori station now has elevators down to the Yamanote line from the JR Transfer section or the JR ticket gate side too!

Sanosuke!

I've just stumbled on this thread, and am glad that I did. I will be arriving in Tokyo at 7:30am and heading to the Conrad. (Does SQ have an arrivals lounge at NRT?) It hadn't occurred to me that would be too early for the limo bus. I've read the entire thread, and remain confused about the best option. I am cost aware, but not a budget traveler. I will have a suitcase large enough to have been checked. Are my two options the train plus taxi, or the bus to TCAT plus taxi? Given that I will be coming into Tokyo during morning rush hour, does that impact which choice I should make?

As mentioned above, the limo bus to the Conrad leaves NaRiTa at 12:50. So if you're arriving at 7:30, you'll probably be out around 9AM (it took me about that long to get through customs and get my baggage the last time I arrived, but YMMV).

If you don't want to wait, drag your bag (I hope it has wheels) down to the train terminal in the station. Take the NEX to Tokyo Station. Then go get in a cab and take the cab to the Conrad. That trip will cost about 5000 yen, and it's not a bad ride at all. The NEX is all reserved, and you'll have a place to put your bag, and you won't be getting into Tokyo until 10:30ish anyway, so the rush will have died down a little.
