Has anyone experienced the AI at the Casa Magna in Cancun? We have a stay booked and noticed that for some reason gratuities are not included in our Price. It seems as though all other Caribbean and Mexican resorts offering the promotion have a true "All Inclusive" price (no extras, no hidden costs). Has anyone else had to stop and figure out a tip even though the meal is "free"? Seems a little chintzy to me. Any thoughts?
