The Grand Mayan has more luxurious units and some additional amenities. They both share common grounds so most of the amenities may be used by either. A guest at the Grand Mayan may use all of the amenities at the resort whereas a Mayan Palace guest may not use any Grand Mayan amenities. At their Riviera Maya resort, the Grand Mayans have their own private pool. This is no hardship as the Mayan Palace pools are much nicer. I would definitely ask for the Grand Mayan.
You are requesting in the off-season so you should have no trouble at all getting a Grand Mayan at Riviera Maya. Bear in mind that September-October is in the Hurricane season. The first time we went to the GM - Riviera Maya was in October and we just missed hurricane Wilma by one week. We had a severe tropical storm that ruined 5 days of our 2 weeks. Now we go only in April.
We have also stayed at the Grand Mayan - Nuevo Vallarta for 2 weeks. It is very nice and their beach is much better, however we prefer the Riviera Maya location. There is no snorkeling on the West Coast plus there are more interesting places to visit at the Riviera Maya.
