Hi, we are sailing on the wonder on Oct 15th to the Mexican Riviera. there is a port adventure we wanted to do, but was sold out immediately. my question is should i just wait for last minute cancellations (we have group of 13) or should i try to contact them directly? i noticed that their rates are cheaper through Disney than if we were to go directly through them. we are really not planning on doing to many excursions but this was one that we really wanted to do. any suggestions?
