Not only did they relax, we did a day trip to Isla Ixtapa with Fred Bouchet of Mero Adventure. We loved it and we love Fred so we highly recomment his trips! Check out his website:

Here are some pictures of our trip, which included snorkeling then a lunch on Isla Ixtapa (at a restaurant that will not rip you off!). I highly recommend getting a fresh fish done "a la plancha".
