Both of the Excellence Resorts have a lot of similarities in the way the lobby bar is set up with that impressive lobby and entry, and the way the rooms are set up and configured.
Differences in location.. Excellence Playa Mujeres is north of the airport, and to get there you are driving through a more of a neighborhood and city... PM is a very up and coming area though, with great beach and protected from waves by the fact that Isla Mujeres sits right off the coast. If anyone is interested in doing whale shark tour or other sailing trip you are right next to the little La Amada Marina so convenient for that...
Excellence RC is south, and a straight shot on the highway to get there.. maybe a little quicker drive.
Both are equal in wedding venues, great restaurants, and entertainment.
If you would like photos just let me know... Wright Travel has a great relationship with Excellence group and can also help if you are not getting prompt reply from the wedding department if you are not receiving quick replies.
