If you would like to start booking your travel, here is the Panama Jack Resort's website:

You will be flying into Cancun, and will also have to include a shuttle fee to get to the resort, which is about 45 minutes away.  Southwest will offer their flights for October in March, otherwise other airlines are currently available.

The Royal Resort (adults only), which is next door, is the Panama Jack's (formerly Gran Porto) sister property, and you can book there as well.  If you stay at the kid-friendly Panama Jack, you must book an oceanfront walk out room or master suite in order to use The Royal Resort's amenities.
