I am going to PDC in October and was wondering if it is better to book any of the tours I may want to do before we go or if we can do it when we get to the resort? Also can anyone give me some advice on which ones they enjoyed. I am going with my husband, 2 kids (10 and 11) and my mother in law and her friend. We know we want to go to Tulum but thinking we should rent a car because we all get bus sick. How easy is that and if it is easy can we just get tickets to some of these attractions? Thanks in advance. I have only been to Florida on vacation so this is all very new to me.
