2 week all inclusive holiday ?

Marmaris, Turkey. Club Alize. Booked through first choice. Family of 4. My booking is one adult and 3 kids not sure what the situation would be if 2 adults and 2 kids were to go but I can look into it if need be. 900 already paid and 2130 left to be paid by April. 2 weeks All Inclusive. Saving of 400 on the total cost of the holiday.
