JM Marriott Masai Mara and Al Maha

we have 7 nights on the ground for the trip in the first week of Sept this year. currently hold a 4-night reservation at JM, and a 3-night at Al Maha near Dubai, all reservations are in Marriott points. worried we will get bored at JM Masai Mara after a couple of nights, thinking of cutting off one night from Masai Mara, to have 4 nights at Dubai, two nights at Al Maha, and two nights at a city center hotel. what do you guys think? we are a H/W couple in our late 50s if it does make a difference.
