The only trip we did on a serious budget (2005), we did bring a toaster. There were 12 of us (6A and 6Kids), and we had three rooms at POR for 9 days. We hit Costco when we got there and got three cases of water, two packs of bagels, one pound of turkey, one pound of ham, two loaves of bread, cream cheese, yogurts, juice boxes, muffins, PB&J and cereal (we brought with)...can't remember what else. We brought mayo packs, plasticwear, paper plates and bowls, fruit snacks with us as well.
We ate out three and a half times. We did Ohana, Sci Fi for lunch, Chef Mickeys and half of us did the Castle for lunch using the DDE card for all. We ate almost all our others meals in our room. We ate breakfast each morning of course, in the room. Then I would say at least half of hte other meals we ate in the room. We did eat a few counter service meals when needed...cause we didn't take food other than snacks and drinks into the parks. I do remember the AK day was one where we ate CS for lunch, but can't remember any others...though I am sure there were.
OH, as for the $6
Walmart toaster, we used it, packed it back up each time to keep it out of the way (it was in FULL view of the Mousekeeping, but not just sitting on the table still plugged in) and threw it out at the end of the stay.
