Single serve pudding cups, single serve applesauce, single serve fruit cups, cereal bars, rice krispy treats, single serve cereal (or regular sized box of cereal and disposable bowls, tuna in foil pouches, peanut m&ms, aerosol cheese, crackers, packaged cheese & crackers, packaged peanut butter & crackers, juice boxes, trail mix, pocket bread or tortillas that are shelf stable, raisins, dried apricots, nuts. On yeah, in my part of the country, Frito Lay just came out with something new called "Go Snacks", they come in lightweight, handy (all plastic) containers about the size of a pringles can. They have fritos, potato "crisps" in original and sour cream & onion, a few varieties of Doritos 3D's and a couple of versions of Cheetos....they are in the chip aisle at the grocery store. They worked well because the chips didn't get smashed in the backpacks and the lids snap on, so you can eat just part of them and then seal them closed again. Although these are more expensive than the chips in a bag, if you just buy a couple, you could refill with bagged items and then toss the container at the end of your trip.
I found UPS cost less to ship that US Post Office, you can call them or check their website (
www.ups.com) and put in the zip code you are shipping from and to to find out delivery time....I shipped to resort so it got there about 3 days before I left (I used the tracking number and confirmed that the package was received at the resort before I lift town (I figured if there was a problem (there wasn't), they could probably track it down in the 2 or 3 days before I left). I had room in the box for our ponchos, extra ziploc bags, insect repellant and sunscreen, so I lightened my load to the airport.
As far as the toaster goes, we stayed at Port Orleans Riverside
and there was a toaster and a microwave oven availbable for (free) use in the food court. I didn't know about this, and hadn't planned on anything that needed to be heated up, but it was there to use. If I had brought stuff to heat up, the food court was right on the way to the bus stop each morning and there were plenty of tables and chairs there, so we could have eaten there instead of in the room. I don't know, but I suspect the other food courts have these available too.
