Thanks for letting Barefoot Destinations help with your family vacation. Per your request, I have looked at dates July 29-August 1 for 2 adults and 2 children. Both resorts are all-inclusive and will include private round trip airport transfers. Dreams Playa Mujeres is a brand new resort that opened this year. It's stunning! It has dual water slides and a play area as well as golf course and great beach. It's in Playa Mujeres, 10 minutes north of the Cancun airport. Paradisus La Esmeralda is a beautiful, luxury resort in Playa del Carmen. It also has a kids' pool and play area, but no big waterslide like Dreams. It is about 45 minutes from the airport and 10 minutes from downtown Playa del Carmen by taxi. I think you will have an amazing experience at either of these. I did not include excursions yet because I wanted to see which one you chose. Pricing is different because they are in different locations and have different options.
In my opinion, given your previous amazing experience at Atlantis, I think you would enjoy Dreams more. It has more to do for the kids with ice cream parlors, pizza, and huge water slides. It's beautiful, luxurious, and brand new. I know Cheryl mentioned Playa del Carmen, so I included the 2nd option. If you choose it, I would recommend upgrading to the Family Concierge Suite. It is in a dedicated family area of the resort with your personal concierge. It gives you expedited service, they customize your stay, and help you make reservations so no waiting for dinner.
The best rates are currently published on Southwest website. There is no bundle discount with Southwest to either of these resorts. I can book these for you, but my air desk charges $30 per person for international flights. Totally up to you. These are the flights you requested, and they are actually at the LOWEST I have seen all season. If you like them, please don't wait. They WILL go up.
