I own Mayan Palace Regency...one regular week per year and one Vacation Fair week , along with the Sea & Sun pack, which would give us a total of 7 weeks at Mayan. I have to say the Grand Mayan to me, is nicer...plunge pool on balcony etc. ( Oh I own a two bedroom lock off). The grounds at the Mayans are lovely and well maintained. I like the resort but I do not get that homey Mexico feel at them, probably cause they are so big and also not sure how to phrase it, more modern or americanized, I guess. They are lovely though. We only pay MF's if we use or band the week thru an exchange company, so it works for us. We do have to pay the one MF, every 5 years irrelevant though. Definately buy resale in my opinion.
I also own at Paradise Village, a small point package. That too is a very nice resort with Mayan touches. Convenient with the Paradise Mall right there. Nice balconies. Less formal than Mayan. Higher point package would be better for most, but for us okay as we own a lot of timeshares. Booking with them is a pleasure, very cordial and friendly.
Playa Del Sol Grande, have only visited but never stayed....nice resort as well but I cannot vouch for service or such.
Good luck in your search for the best deal......I wish you luck!!!
