This is why I love blogging, people. As soon as I published my plans for the summer vacations, readers started writing in with useful advice. I'm still very unfamiliar with the US geography and am likely to become completely lost. Mike, a fellow blogger and a resident of Florida, suggested that travelling to Tampa will turn out to be much cheaper than going to Daytona Beach instead.
So I did some research, and, of course, it turns out that Mike was completely right. I found a much higher quality hotel in Tampa for $350 less. So, of course, that's where we are going. I'm very happy.
Thank you, Mike! I owe you a huge drink.
