If you book cash rate, the difference is around 2k. 5-nt stay If having a pool is a must, then spend the money to upgrade to one with pool because your point upgrade is worth over 4k. Or, you can fill the tub and turn it into a small pool as you can open the sliding door to the patio and save the point/cash :-) We only use the ow patio for morning coffee and when we snorkel so for us it would not be worth the cash/point upgrade
