I'm throwing a housewarming open house tomorrow afternoon and I'm making a Costco run this afternoon to get the majority of the food for it. So far we're having BBQ brisket sandwiches, tortilla chips with various dips, fruit tray, veggie tray, and I'm planning on getting 2 more apps from Costco to have. Anyone know of a good appetizer they have that I can heat/thaw/whatever and be OK left out for a few hours at room temp?

Secondly, it's also my birthday (what what!) and I can't NOT have cake, so I was thinking of a Costco one. If I get it this afternoon, will it still be OK tomorrow afternoon? I'm planning on also having chocolate tarts and various cookies. I was going to get a vanilla one.

Thoughts?
