You may still need to do that when it goes down for weather, which it will during the summer storm season. But maybe they'll send you to a Crescent Lake resort for a bus. There's no set procedure for it, which is the problem, as is the lack of communication. Don't get me wrong, the Skyliner's a fantastic mode of transportation when it's working, but when it's not...lol. Having seen an absolute clown show back in 2019 when it had been down for hours at the end of the night on a Saturday during F&W, and lesser fiascos literally every time I've been to Epcot in the summer since it came online, I would never stay at a Skyliner resort. Not until Disney gets it together and has some kind of standardized contingency plan for Skyliner resort guests.
Re: the OP I thought about Pop once or twice but ended up booking CSR instead. By every metric besides transportation and price it's a better resort imo.
