Buy where you want to stay can be good advice, it can be awful advice.
First ‘hurdle’ is have you actually stopped there for at least 4 nights?Many people say ‘I must by VGF (BLT, AKL etc)’ based on walking through it and thinking they’ll love it. It’s quite different to stay there and some people regret buying where they thought they’d like to stay. I’m assuming though you’ve stayed at BLT and love it.
Next is type of room you take and time of travel. If it’s a 1 bed, off
DVC season, you can easily get BLT Lake View at 7 months and I don’t see it changing. So if you fit in this bracket, buying where you want to stay may mean large unnecessary extra expenditure.
BUT if you want to go at Xmas, in a studio, have to stay there and want a theme park view, my advice would be buy where you want to stay.
Another thing is the potential for SSR to grow in value. I think DS has already made it more attractive, but it’s quite widely believed there will be alternative transport put in near SSR or DS- possibly a skyline extension or even a monorail / light railway type thing, the latter seems as though it is being considered now if well respected tipster Marni has good info, but it’s very early days. I do understand guides have been pointing out to direct buyers of SSR ( and they didn’t do this to me) that those easements for a transportation system are still in the Declaration of Condominium.
I do think Disney want to knock out as many buses, and drivers as possible long term.
