[QUOTE=tagor;8418509]I would really appreciate some advice, both with choosing a hotel, and method of transfer.
We have a stop over in London on October 10.
We will be flying IN to Gatwick on Oct 10 at 3:00 PM, and then Flying OUT from Heathrow on Oct 11 at 10 AM. /QUOTE]

For one person, the most cost effective way to transfer between LGW and LHR is the National Express Bus -

www.nationalexpress.com

The service links both terminals at LGW with both T4 and T123 at LHR. The fare is about 19 GBP one way.... If there are enough of you a pre-booked car might be worth it

I think the buses tend to depart from the South Terminal, call at the North Terminal - head to T4 and then T123... (for hotel shuttle)

Leaving Gatwick at around 4pm would (given the rush hour) get you into LHR123 (with some margin of safety) at around 5:30-6pm (the schedule is less but the traffic can be nasty)

I will leave it to others to reccommend LHR hotels - I live too close and have never stayed in any..... If the flight is from T4 - I think the Jury's Inn and Hilton are close.....

If you are going into London - note that the "Southern" train also serves Victoria from Gatwick and is a little cheaper than the Gatwick Express. There is a Circle Line tube train from Victoria to Paddington but it sounds like you will be there in the rush hour so a taxi could be better (there are even direct London Buses for the adventurous !!)

There is a Hilton Hotel at Paddington Station itself and plenty of other hotels around.

Another alternative is to put yourself somewhere on the Piccadilly underground line overnight . This line terminates at Heathrow (both T4 and T123) and passes through South Kensington, Gloucester Road, and Hammersmith on its way through from central London .... (the journey would be between 25-40 minutes into Heathrow the next morning) These areas have plenty of hotels (certainly the first two)

The Picadilly line is certainly not as comfortable as the HEX - but there is limited provision for luggage and certainly it is used as a way to the airport with bags - depends on how "much comfort" you want though !!!


There is more on the tube network on the transport for London website...

www.tfl.gov.uk/

The website has Maps and even accommodation searching functions - relative to the tube lines



BUT.......

If you have no desire to see London at that stage of your journey

I would do as previously suggested - avoid it - and get the bus around to Heathrow.....and have a quiet night in !!!
