Pregnant at Disney World?!

Allyson
Hi ladies! So I recently got my BFP and have been on cloud 9 ever since. There's just one thing making me nervous- my family has a Disney trip scheduled in October, when I will be 7 months pregnant. 
I've done lots of reading about it and I think it should be ok, but I can't help but worry that for some reason, I won't be able to go. 
Anyone gone through something similar? Let me hear your stories!
