We are headed to Disney in November and we have a "pop up" site reserved, but we are in the process of upgrading our camper situation. The travel trailer we are buying will be the same length and width of our current pop-up (or really close). Will we be ok? I called Disney but they said we have to have a pop up in the site. We obviously don't want to travel across the country with a camper we won't be able to use...any advice? Just do it and they won't care? I saw somewhere else that it should be fine, but I would love some more expert advice. Thank you!
