I'd have no worries walking home after a game, personally. But you could also get a cab (though I'd probably walk a bit away from the game, just to make it easier). Or take the subway (which, I think, is better than the bus for what you are doing, because the only bus that I could see being helpful is not nearly as frequent as the subway) - the walk to the subway or bus is probably almost halfway to the hotel though.
I measured and the walk is about 1.6 miles (I run marathons, so sometimes my version of "walkable" isn't the same as other people's, so I thought I'd figure out the real distance).
PM me if you'd like more specific walking/TTCing (our bus/subway system) details.
