You have a lot of really great stuff...but I can think of a few more items.

Toaster or toaster oven...or BOTH!
Ice Cream Maker
Blender
Kitchen Aide Mixer + attachments
Dishes
Bakeware
Fun summer dishes/plate/cups
Laundry Hampers
Extra sets of towels and/or sheets
Kitchen towels
Pot holders
Mixing spoons...or other kitchen utensils
Cookie sheets

Hmm...if I think of anything else, I'll let you know. The idea is to provide your guests with lots of items to choose from. They do want you to have something you'd enjoy. Put stuff on there that you wouldn't want to buy yourself...but would enjoy - like the ice cream maker.

How fun! I bet you're getting so excited!! Its 2 months away today, right??
