We're going in May as well! But not until the end of the month. (boo!) We have DVC though so I don't know much about hotel prices. We often rent a car but it's in part because 1) we get groceries for the room, and 2) we usually combine the trip with going somewhere else like a cruise or my mom's house in Tampa. So this time we will rent a car in Tampa and then drive it over. We've just used Budget the last couple of times because we haven't needed to return the car ON Disney property. We actually used Uber last time instead of the Magic Express because they wanted us to get up a lot earlier in the morning than what we wanted to drag the kids out of bed!!
