I booked a standard double room by single rate (17,000JPY) from HP. I am a MR-Silver member but MR hotels in Asia and Pacific offer the room upgrade and free access to the fitness for the ANA(NH) Dia, Plt and SFC members, so I could get a DX twin room (38m2) on the 33th floor.

Thanks to
Yasuki's help evaluating the Hilton vs the Marriott (both chains where I have top status), I settled on the Marriott. Convenience to the train station was the driver.
At Nagoya Airport, follow the clear signage to the train station. There, you will find excellent signage giving the fare for Nagoya: 810 yen. You need cash to buy your ticket. You get a little magnetic card that you use to go thru the gate.
The first couple train cars have reserved seating. Go beyond them to a car that says unreserved seating. The train makes several stops enroute to Nagoya, and will fill up enroute. It takes about 35 minutes.
When you get out at Nagoya Station (the terminus of the line), follow the signs to West Gate. When you are outside, look across the street and up. There is the Marriott.
Walk into the hotel, and take the elevator to the 15th floor. That's where check in is. We were given a spacious room on the 47th floor, with Executive Lounge access. There is a sign in the Executive Lounge that golds and platinums get access, along with those who have paid for Executive Lounge access.
Our room is considerably more spacious than that reported by
rtwstaralliance. In looking on the floor map, there is a considerable range in room size, including rooms much larger than ours. We have a nice view over the city, 2 arm chairs, desk, dresser, dressing table, and king size bed. The bathroom has a separate shower from the tub.
Executive Lounge
The lounge is open from 6am to midnight. Reception is staffed from 7am to 10pm.
6am-7am Continental breakfast
7am-10am American breakfast
5:30pm-midnight cocktail time with a modest assortment of appetizers
A 3pm checkout is offered if available.
Takayama
For those without rail cards, here are the fares to Takayama:
3000 yen one way - slow train, takes about 4 hours
+2500 yen one way - rapid train, takes about 2 hours
From Nagoya Station, take 20 minute ride to Gifu, then change to train to Takayama.
