Agreed. There is no way to prevent that from happening but they could make it challenging....they may choose not to offer complimentary transportation from the resort. They would most likely schedule immersive missions and activities that you would want to participate in throughout the resort and Galaxy's Edge since you are paying top dollar. I doubt there would be a lot of free time go out and ride Soarin. I think the key to this is a relatively set schedule and limited timeframe at the resort (check in on Monday and out on Wednesday then move to a more traditional resort to experience the rest of WDW).
Yes. I don't think they will prevent anyone from leaving the resort, but they aren't going to make it convenient to get anywhere else. Even if it is built near/next to DHS and SW:GE, I think the transport to there will be available only during a designated visit to the land (likely after hours) and not open at other times to visit DHS. They are going to try to discourage anyone leaving the experience.
And I think there's very little chance that anyone not staying would be allowed "on board" to see the festivities.
I wonder if they won't rotate buildings or floors out - Day 1 and 2 you are "in" and days 3+ you are at a "regular" resort - I can't see them discouraging guests from visiting WDW - otherwise why even locate it in Orlando?
Well, sure they want to also visit WDW. That's what the
other 5 days of your week long vacation is for, after your 2 days doing Star Wars cosplay. They will surely sell combined packages for Star Wars + WDW (like the land and sea stuff with the cruise line).
I think the question easily applies to families too. Dad and kids are all in with the "experience". Mom, not so much. Mom just wants to mimosa and chill her way through until Mickey Mouse!
The more I'm thinking about it, I wonder if they might have a specific available non-themed area to allow less interested members of a party to "get away" from Star Wars and go to the pool or get food, whatever, in a "normal" manner. This would allow guests to self segregate and prevent those guests from "messing up" the experience of the more intense guests, but being more realistic for groups of mixed interests. I mean, the stay won't be any cheaper for those folks so Disney won't care and if it keeps them from wearing crocs and Mickey ears to the local SW cantina, then everyone kinda wins.
They just would need to make such an area set up so that you won't accidentally wonder into it and break theme. Probably have CMs in character who make sure that guests want to leave the ship and go "to Earth" before they leave the attraction.
