Some suggestions I would have from my experience on the tournament trail are these:
Do the player draw in full view of everyone.
Provide hotel informations WELL IN ADVANCE of the event, phone number and address, for those who may be traveling.
Also, though it may seem like a given, please do provide the pool room's COMPLETE address and phone number. This helps players with logistical arrangements for travel.
It may be helpful to let the tour members know what percentage of monies are taken out of monies to keep the tour running, to avoid unnecessary hearsay and speculation.
I like the 25-percent payout of the field. I have attended some tours that pay out 40 percent of the field, and for the player who gets a check for $25 after hanging out for two weekend days, it really doesn't mean that much. IMHO, at least for the players I know, more money at the top gives players something to shoot for.
Some pool rooms have great food, and others have what I refer to as "blood mud" food, fried cheese sticks and potato chips, as an example. I have been to some pool rooms who make a special tournament lunch for the tournament days. The players would rather eat in the room than have to go elsewhere because the food in the room sucks.
Most importantly for me is that the TD shows no favoritism. If Efren Reyes comes in 5 minutes late for his match, then he forfeits -- NO EXCEPTIONS.
Hope this helps!
