Well, as far as tickets go, I wouldn't compare this to any other tour, but I might agree that the early rounds will be a hard sell. Maybe not the first year though, the first year each tournament will most likely sell out due to it's something different and new.
Some events and shows I have attended have advance admission at lower price then the door tickets, and sometimes they offer things to advance admission holders like maybe early admittance to see practice or meet someone or say get promo item, this actually works in getting people to buy early.
The package deals work well if there are multiple days and tickets, I often fall for a 4 day pass or a 3 day pass at a special price, I may originally only wanted to go one day

this twists many peoples arms and they end up spending more then they were going to and fill the event
Often you can get business to give you something for free to give out, in this case say a promo tip tool to give away as a promo on a certain day, so if you have 5 day event, this can get people to buy passes and actually attend every day. You would be amazed at how many people would go a certain day just to get a little free widget or hat

Something like, first round all attendees receive a free limited edition IPT 8-ball hand towel....it cost almost nothing promotes your tour and people are crazy and fall for this like mad.
I think all the marketing will fall in line after the first few tournaments, you can't really make these decisions without first seeing what the demand is going to be. I don't really have a problem with no door tickets, but they could always say only 50 tickets available at the door for back row seating only most NBA teams do this when they sell out anyway.
I've done some work around promotions and marketing, I find it to be a blast. Sadly pool has never really done much marketing of itself
Just having a guy like Deno to listen is a HUGE step in the right direction for pool!
Bravo Deno!
