@Donald - my hero ,
@bababear_50 and anyone else who may be interested in a get away - my hubby and I went to Riviera Maya Dec. 28/16 - Jan. 4/17. We stayed at the Iberostar Grand Paraiso. To say the hotel is a 5 star is an understatement. Anything we could have wanted was taken care of, we wanted for nothing the entire week. Believe it or not, you can have lobster for breakfast, lunch and dinner if you were so inclined. It's an all-inclusive, even the 'specialty' restaurants were included.
The Iberostar has five hotels in the Paraiso complex, with the Grand being adults only. Also, guests of the Grand can access all 5 resorts and their respective restaurants, pools and other amenities, but only Grand guests can use the Grand facilities/amentities, etc.
We booked the package through Air Transat, so I know you can use your AM travel certificates for it, which is good, because the price per person is pretty steep. My 50th is in March 2019, and we're taking the 'kids' (28 & 25 by then) and their respective partners with us either to the Grand, or to Greece, depending on where everyone is at budget wise by that time. That's what I'll be saving air miles for from now until then.
