Hello We are visiting 13 - 20th Oct. Wondered if anyone could answer some questions: 1. Is the timeshare tour informative even if not interested in purchasing? 2. We are planning on going to Chichen Itsa is it best to book through hotel? 3. Does the hotel do to a trip to Coco Bongos? 4. How much money do you need a day for tipping? 5. Any recommendations for best places to do some shopping for local products? 6. Any must sees or other tips?
