I just heard back from Mazatlan Frank. Unfortunately for me, he is already booked on the city/beach tour on our day in port (May 3). He invited us to go along on the one he has going, but I have already done that tour and was really looking forward to something new.
He mentioned one of his friends could do it, but I do not have the required number of people. Is the tour the ship offers that much different than Frank's?
