This was a great option for our family of 5 while visiting La Paz. Our rental was spacious - 3 primary suites living room, kitchen, laundry.
Our kids loved the pool and hot tub and the easy access to the beach and volleyball nets. You can check out a volleyball from the tienda on site, but the kayaks have to be rented.
Taking the ferry to and from the resort was not overly onerous, but we did have to keep an eye on the ferry schedule.
