3-weeks! That's a good chunk of time. Do you work from there on a longer stay like that? Or do you just holiday? We'll be there in October and November.
Some more info about Basin Glacial Waters that I've learned:
BGW is a totally separate entity from the CLL Fairmont Spa and will not bundle services at all. There goes the hope of using insurance to cover the cost haha. The Basin will not be offered as a perk for HERA, Virtuoso, etc. for the foreseeable future either. I did notice in the ALL app that you can book BGW as an add-on when booking a room in the late Fall now and I don't see it as an included amenity in any room tier at this time. They truly want to keep the Basin experience as an exclusive thing. I wonder what it will look like in peak summer in 2026 though when the property is at capacity. Lots of time to test it until then I guess.
