There is a coffee maker in the hotel units. There is no floor plan because the units are very different depending on where they are on the floor. The beds are a King (or Queen) in the regular hotel and I'm not sure about what is in the double...but I'll find out in January. There is a table that pulls out from the under the desk and a desk chair. I can't remember if there is another "puffy" chair or not in the regular units.
There is a little deli next to the resort on the corner. He makes great breakfast sandwiches for a couple of bucks. They have a "per pound" hot and cold buffet and grocery items. There is also a fruit cart (maybe not in the winter) across the street. Diagonally across the street is Dunkin' Donuts, Burger King and Subway (and Hofbrau). There are New York pizza by the slice places (cheap pizza) nearby. The diner across the street gives you a discount for showing your Wyndham room key. There are groceries available at the Amish Market (towards the UN) and at Grand Central Station.
DON'T bring a vehicle. Parking is over $50 per day. I suggest getting a transit pass (7 days unlimited is $32) good for all buses and subways. I take public transportation from the airports. Express Bus and then Subway from LaGuardia. Train and then Subway from Newark. I don't fly into JFK usually, but there is the AirTrain (Subway) and then Subway.
When walking, the east-west blocks are really long...some are 1/4 mile. The north south blocks are "regular" and short. The resort is on 3rd. The Theatre district is on 6th-9th...mostly on 7th. It is over a mile...plan on at least 20 minutes at a good clip. OH! If you are taking the 7 train, get in the front car and take the exit by the front car. Up a short flight of stairs and then a HUGE escalator. You come out on 42nd street across from Capitol Grille. Go to the right 1/2 block to 3rd and then turn left and walk up 3rd Avenue to the resort. You will pass a CVS and Duane Reeds and lots of places to eat. Reverse the route to get to the 7 train. This is SO MUCH easier than wandering around the maze that is Grand Central Station....and is a shorter walk than the way the resort tells you.
There is a bike rental just outside the resort, as well. Enjoy!
