It means nothing. I sail on Royal Caribbean frequently, and they are just another part of the food offering. I ate at CP's a few years back, and it simply enhances CP's basic foodservice operations.
They command top rent, so I can't see Synder pulling them back from other non SF owner entertainment offerings and locations. There is no SF in CP's market, so it would stay.
I have seen JR's in outlet malls owner by the Glimmcher Group, and at Bally's Park Place in Atlantic City. You wouldn't exclude them from other casino or retail companies. JR's competition is from Fatburger, Steak and Shake, etc.
Like Cold Stone, JR's can only help a theme parks foodservice offerings.
Harborplace here in Baltimore had one (I think it's still there; haven't been there in ages), and Arundel Mills Mall by the airport has one. I've eaten there, and it's OK. Now, put a Cheeseburger in Paradise in my local SF, then I'll move in.
2. Virtual que system, for the right price you can cut the entire wait list.
Hehe, if you frequent restaraunts that get long waits and have other ways to spend your time - it's pretty easy to 'virtually' wait for a table while getting other things done and then 'walk-in' to a spot in the restaraunt a little later. (a lot like the standard Q-bot)
I couldn't tell you the last time I stood around outside a restaraunt waiting with the masses for a table.
