Absolutely horrible service. I worked with Lian Alston for my cousins wedding in Cancun. I followed all directions specifically and gave all of my flight info and my wife's flight info ahead of time.
Upon arrival, I was transported via AmStar ...with no problem. I was with a lot of the wedding invitees. My wife, however, was arriving the next day. Honeymoons, Inc. advised me that I should still pay for her in the room for the multiple day package because it would be cheaper, even though she would only be there for two days. That was annoying, but I followed directions.
My wife landed in Cancun and was not on the AmStar list. They had her down as already using their transportation with me the day before, since we were married. This confusion was not properly communicated by Honeymoons, Inc. and so my wife was stuck at the airport for quite some time. The AmStar officials were extremely rude to her, cussed in Spanish, told her not to move, took her passport, and really freaked her out. Her vacation was ruined. All we got was a sorry for this.
Upon leaving, several guests, including me and my wife, were denied AmStar passage and were forced to take an expensive taxi.
I got back and complained to Steve and Lian. They asked me for confirmations of flight emails (as if they didn't believe me), I clearly showed it to them, and then their only resolve was a pointless $200 "voucher" that has a minimum flight + 3 night stay requirement within 10 months of my receipt of the voucher.
It was an awful mess. The part I regret the most was that the bride's dad was super worked up, along with several guests.
If you book with them, be very afraid of communication with scheduling rides and weekend travel. They don't do much to help you after the problems!
