Souvenir sets neccesary to win Tokaido? My wife and I have probably played Tokaido a dozen times since she picked it out (because she liked the cover artwork), mostly with the base game and occasionally with the Crossroads expansion.  In the base game, it seems to me that the winning strategy for any character that's not starved for cash is to hit the market and try to get complete souvenir sets.  I've seen this enough that I'm wondering how feasible it is to win without buying souvenirs.
