1. Both? Haha.
2. Yes, primarily due to potential downtime. If it's up and running, do it.
3. Pizza Moon, Oak & Star.
4. Your call, but child swap was a breeze for us, and we got to enjoy the queue, which I feel is an integral part of the experience.
5. It's about 30-35 min once you're in the Atrium, if it's all smooth. The TM's probably won't say anything, though, due to possible delays.
6. Astronomica seems to have just opened a couple of days ago, so there probably isn't too much experience. Viking Training Camp is great and rivals Camp Jurassic in terms of activities to do.
7. A good chunk, yes!
