I'll go to AC if Yuzuru does. I live in NYC, so flights are fairly inexpensive & quick to Toronto & Montreal. You shouldn't need to camp out every night for tickets to AC; you just need to get to the rink early. (In Barrie, fans who were trying to camp out were told to leave.) In Barrie, we had to stand in line for a few hours on the 1st day in order to get tickets, but we could buy tickets for all 3 days at that time. The other 2 days, we just had to get to the rink early to secure good seats. I hope the same system is used in Montreal. Even for late-arriving fans, there were seats in the 4th & 5th rows available. If you do go, message me.
If Yuzuru retires after the Olympics, or after Japanese Worlds in 2019, that leaves limited prospects of seeing him at competitions for which tickets are obtainable & fans can go to practices (that is, not competitions he does in Japan, including the 2019 GPF, & not any GPs other than SC & SA). I hope he does SC or SA in 2017 & 2018, a 2018 Canadian GPF, AC 2017 & 2018 & Milan Worlds - & I can go to all of them, but who knows if he will? I'll still want to go see competitions when Yuzuru's not there, but watching Yuzuru at 40-minute practices, 3 days in a row, & then watching him compete, is a special experience I don't want to miss. So, when budgeting time & money for going to see skating, I keep that in mind.
I wouldn't spend the great deal of extra money it costs to go with a tour. I don't think there'll be any problem getting taxis to get to & from the arena in Mississauga or Montreal (there are also public buses & uber in Mississauga; I haven't researched Montreal yet), & paying for that, plus a hotel & ticket & food, would likely be much less expensive than paying for a tour.
