I am perhaps missing your point, but if people will be able to experience incredible VR worlds, couldn't people happily spend their time sitting in tiny windowless rooms rather than physically travelling to a beach?
I think there might end up being a greater division between "IRL places you really need to be IRL to enjoy" and "IRL places that are good enough in VR."
A beach seems like the former, and cities and minor attractions seem like the latter.
