This is going to sound ridiculous, but I honestly don't know if we have a gas hot water heater....we just moved in July, and I let my other half handle all of those details. I have several ice chests, so if that words (or if my gas stove lights up without issues and I can heat up some water) that sounds like a workable solution and I wouldn't have to run out and buy anything! I'm glad to have asked and have all these options!! Now to see if we can deal with the temps and don't end up at the hotel anyway!
