^^It's done on a park by park basis. Some parks tell you to remove them before entering the station and some parks it's against the rules to remove them before you are told to do so in the station.
^That's a bummer to hear. The habitat looked really nice but it was quite clear when I visited that it wasn't going to work. Hopefully the nets are only a temporary fix.
^I would absolutely suggest that. That way you can stay later at SFGAd (El Toro night rides!), then get up early the next morning, do Dorney for opening and a half day, then off to Hershey!
^Like you said, Disney is a big Summer Time cruise line with all the kids out of school and deals are few and far in between. You can keep an eye on last minute deals, but don't expect much. If you're willing to branch out I know that Freedom of the Seas (also goes out of Port Canaveral) has had a couple of deals pop up for the summer but you'd better act fast!
^It's always a crapshoot. They could take that promotion down any day or leave it up forever. Also somewhere on the RCCL site is a crazy list of what discounts can be combined and which can not! I believe resident and booking next cruise discounts can be combined, but I don't want to say it for 100%.
Oh! I had almost forgotten about this multi-year project. Yeah I thought we decided last year that it was going to be a wing rider. Especially with Merlin involved! Not a fan of that type of ride, but it looks like they'll at least do a good job with fly throughs and theming.
