Why not just buy the pirate ship tickets and save yourself the sales pitch? Seriously. Why would you want to waste time listening to a pitch for something you're not going to buy anyway? I got sucked into a timeshare sales pitch in Cabo years ago (very pretty girl, pleading and begging me to attend, and I was a sucker for it). I'd NEVER do it again!
On the other hand, we went down to the Mayan on our own one day to check it out. Had lunch and some drinks on the beach, looked around. Nobody tried to sell us anything and that was fine by me.
I haven't seen the pirate ship out the last couple weekends I was down; I think business was just too slow.
