I took our crockpot on our last trip in 2009. We were staying at Fort Wilderness Cabins.
It was the best decision ever!! We are a family of 6 and each morning before heading to the parks, I put all the ingredients for that day's meal in the crock pot (buy the liners to make easy clean up) and when we returned at 1 or 2 in the afternoon our meal was waiting.
Loved, loved, loved having the crock for budget reasons and for a home cooked meal on vacation.
After checking into the cabins when we arrived, we dropped of the kids at the cabin and headed out to
Walmart to buy the fresh supplies we would need for the menu I had preplanned. ((Did not like the fact that I had to go grocery shopping as soon as we arrived, but the sacrifice of park time then was sooo worth it later.))
We still talk about how nice it was to come back to a meal prepared and how much it saved us in feeding 4 hungry kids on that trip!
Would easily do it again in a heartbeat!
By the way, I found great crock pot recipes at the Fort Wilderness/Camping thread.
