Yes, you will find a hairdryer and coffeemaker in your room at the WL. If the fridge isn't there, just call housekeeping or ask the cast member when you check in and they will bring it right up. The Mercantile at the WL sells lots of grocery items - milk, juice, soda, water and snacks. We loved that we were able to get 1/2 gallons of milk for our kids.
There is also a set of drawers as you enter the room which I found to be SO convenient to keep all of my kids' things - diapers, wipes, snacks, etc.
You will LOVE the WL! It's our favorite! Have a wonderful trip.
