We will be staying at Moon Palace the first week of May 2014 and would like to do a day trip to Isla Mujeres. What would be the best way to go about doing this? Has anyone taken the Isla tour from palace resorts and have any info on it? We would really like to go to the Palace Resort on Isla Mujeres (no kids with us) for lunch and to spend some time on the beach. Would like to do some snorkeling but not at the Eco Park there (Garraffon, I believe) as their admission cost is outrageous... any suggestions? Thanks!
