Friends in Punta Cana spent a total equal to about 7-8 hours (2 or 3 separate presentations)..ended up with about $300 plus gourmet breakfast plus whalewatching tour. Said it was worth the time they spent since they were there for 3 months. They knew they weren't buying anything and they said so did the "sellers"...they just needed to bring the bodies in. Anyone find any of these worth the time for the armtwisting??
