With us it has varied between hours and weeks. bborst is right - there is no way to know (in advance) how long the process may take, or even if it is going anywhere.
Generally we prefer not to play on the first meeting, as we like to get to know potential playmates to some extent before getting down to the nitty-gritty. We don't let that preference stop us if all lights are showing green though
The desire to know a little about potential playmates is what has so far stopped us from trying out the clubs, though it's looking like we may do that anyway. Red announced at the weekend that it could be fun and I should know her well enough by now to spot that green light!
