We are staying at the Riu Jalisco all-inclusive resort in Nueva Vallarta (about 10 miles north of Puerto Vallarta). The nice thing about this particular resort for families (alas, not us....) is that they have deals where kids under age 12 stay free. Yes, that is right. For one low price, you get a room, all you can eat and activities galore for the whole family. There are activities off the resort that you can pay for (run by other companies), for snorkelling tours, hikes, scuba, etc. These cost extra, but all activities on the resort (boogie boarding, they have a small snorkel trip, other non-motorized activities) are included. Very stress free.
We have not yet booked a trip, but I want to do the all day snorkel trip to the Marietas Islands, which is supposed to be just awesome. I want to do it Tuesday or Thursday, but any day would be great. This and many other tours are through a company called Vallarta Adventures (I think their website is www.vallarta-adventures.com ) We want to book something tomorrow from home, since you save 10% or more. Should be a ton of fun!!
