~~~ casino tours thru the years where club members took club members about.

Personally (...and this is only first-hand advice to those who might consider such a trip), any extensive journey such as yours should be well-planned out in advance; such as writing the casinos one plans on visiting to inform them of your collecting interests... and in most cases a simple pop in to the reception they will find something awaiting them. In (actual) fact, many casino managers/operators will go out of their way to assemble material from several nearby casinos in the region in order to help complete a collection. Some of the rarest-of-rare collections have been amassed in this manner (but not overnite ). Enjoy the balance of your stay in Europe.
