I went to Universal when I was preggers...wow...11 years ago!!! I was told that the baby is very well protected in there (in fact, I proved it once by falling ON it with child #1 and that explains alot about him!) but that rides that spin and/or drop and therefore pull the fluid and blood flow away from the baby are bad...bouncing around, while they will say that pregnant guests shouldn't ride to cover their butts, really shouldn't hurt the baby at all...but tight and/ or prolonged spinning is bad...I'd say no to MIB, Spiderman, probably popeye although that spin is really a broad spin...the coasters, of course...Storm Force, Cat in the Hat (do they still have a non spinning car?

), Jurassic park and Dudley Do Right are probably best to stay away from too. Others are a matter of comfort and preference, I'd say...Back to the Future is very bouncy and honestly, I did it when I was preggers but I don't like that one, in general as I usually feel like I've been abused after I ride!
Probably should avoid happy hour too...
Just drink PLENTY of water...and take frequent rests...it's easy to get dehydrated anyway, but in that state, it's even more important to keep hydrated! Some of the attractions that are in a theater and the seats move have non-motion seats, if it were me, I wouldn't bother with the non-motion ones, because bouncing is just not a crisis I don't think! Heck, I bounced plenty just walking!!!
Take it slow and enjoy...and yeah, relax by the pool...if this is your first, it ma y be awhile before you can do THAT!!!
