Yes, definitely be aware of where the restrooms are, and don't forget to hydrate, hydrate, hydrate. I was a hormonal crazy mess a few times on our trip when I was pregnant in 2005. It was September, and hot and we were traveling with friends and their 3 year old. I reached my breaking point more than once, usually when there was food involved. LOL! I'm not much of a thrill ride person anyway, so that part didn't really affect me, but you definitely need to make sure you take your breaks and don't overdue yourself just because others in your party are go-go-go.
