Just do whatever you want, I quit hockey a few years ago too and I don't regret it. It does suck because hockey starts before ski season and I do miss it, but when ski season hits I wouldn't want to be playing.
The thing is, if you decide to join a team you have a commitment to them. If you decide you don't want to play anymore, you let your team down, which sucks because you'll most likely devolope relationships with team mates. Also if you do get a season pass and don't want to ski you waste a lot of money.
Really though it's up to you, do what you want.
