Hi Michael!
Thank you for bringing your question to the Disney Parks Moms Panel!
Michael,
Pandora - The World of Avatar is the most amazing new land. Whether you're a fan of the movie,
Avatar, or not, you're going to be in awe of how beautiful this place is.
Both
Na'Vi River Journey and
Avatar Flight of Passage are indoor attractions. They both have cover over part of the queue, but not entirely. So, you may get a little wet waiting in line. The good news is that rain in Orlando is very common and usually short-lived. Throw a poncho in your bag and you'll be just fine!
If you have a chance to see Pandora at night, then please do! It's gorgeous during the day, but breathtaking at night.
I hope this helps! Please let me know if you have any other questions.
~Lori
