We went for the first time in Dec. We do not cook in the room either so that is not an issue for us. We did go to Winn Dixie when we were there and loaded up on water, gatorade, etc. I brought the pre-measured coffee filters with me and a suggestion I read on here before I left was to bring those laundry "tabs." You just drop 1-2 in start the load. I thought they were very convenient. There is a start supply of Palmolive, dishwashing soap, bar soap, etc. Two separate days I asked a cleaning lady for a few packets of dishwashing soap and they did not hesitate to supply these extras.
Don't over pack, is the lesson to learn. Although, I think I am still learning! I've always packed too much, and have to learn to cut back myself. Having the washer/dryer in the room is the absolute best thing! I was in heaven!!
Have a great trip!
