I just returned from Los Seunos with my wife. It may have been timing but most of the guests were retiry age from the northeast (obvious NY and Boston accents). SO depending on age of your kids they may not find others to play with. They do have some kids activities from time to time. That said the resort is beautiful and as others have stated the service is excellant. Volcanoe tours are not near by. 2-3 hours as I recall. We did take the kayak tour and the canopy tour. Both very good. The zip lines were shorter then others I have experienced and not as fast, so a good choice for newbies. I highly recommend the restaurants at the arena, in particular the Italian restaurant. Can't think of the name at the moment. The bar there, The Hook Up, has a happy hour, but be sure to ask for the happy hour drinks (local alcohol).
