Oh, yes, good idea about the decorations. The only problem with the corresponding walking trail, as I envisioned it, is that the skating trail is on a frozen lake... but, I believe the city of Edmonton has a system of skating trails throughout the city, so perhaps a method used to connect the hotels in the winter could use something like that. The Netherlands hosts a famous long-distance skating competition called the Elfstedentocht (roughly, "11 city tour") through their frozen canals. So maybe this could be the inspiration.The skating trail could be marked by decorations, so it can double as a walking trail when it’s not icy. Speaking of that, the Yetis could be a Halloween event. As for location, I think Alaska, because it lets us use the lion’s share of the Marvel cast and to mesh with Aulani being in Hawaii.
I'm not a Marvel fan, so I'm keeping that group of IPs out of my imaginary ski resort. But don't let my personal objections stop anyone else from dreaming up something Marvel-related. The only bad idea here is not having an idea.
