Welcome Home!!!!
Here are my tips:
Coffee:
If you drink coffee, they have a coffee maker but the coffee packs in the room are not great nor enough. I make up "coffee packs" and put in a sandwich bag and then all in a gallon zip lock bag. So, in a kit: I grind the beans for a 12 cup pot. I include my coffee filters for each pack of grinds. We usually drive and just take a Coffeemate, but, this could also be put in a quart bag. I make one pot for each day and I add 2-3 extra. Sometimes you might like some in the evening or one isn't enough if you are lollygagging around. We also buy the disposable coffee cups with lids to take that last cup of coffee with us to the bus stop. When we drive we also take 3-4 gallons of water-taking Megabus this next trip-so will probably have to buy large waters in the gift shop.
Laundry:
They provide detergent, but, not enough. And no fabric softener. For whatever reason I like doing laundry there (probably because it is free!). I found some Purex all-in-one sheets (detergent and fabric softener) that I am hoarding. I haven't found any more. Once gone, I will probably start taking the small detergent gels that are out now, but put them in a ziploc bag and a bag of dryer sheets.
Miscellaneous:
Ziploc bags-all sizes-more than you think you might need.
Wine opener if so inclined.
Wine-see above
We take one bottle of Gentleman Jack-drinking in parks gets really expensive
pop up laundry baskets-keeps it tidy
If driving--good chef's knife
There is a list of everything in the room on the DVC member site. If something in your room is missing, they will be glad to replace it.
