I chose BOB over MLE based on my own research.
This was debated in the BOB thread and in other threads on DDF, from what i understood is that people choose MLE over BoB is because
1.MLE has better premium airline cabins
2. Much better airline award availability VS BOB
3. Easier to secure a OWB with points
I don't need premium airline cabins, I already experienced every First class cabin on my bucket list. ( I was so able to fly to BOB in F and J thanks to the MR promo)
Also, for me the hard product is the nature and not the Hotel, which according to my research BOB wins.
I wasn't biased for BOB, i made my decision based on my homework.
Regarding snorkeling, BOB has amazing snorkeling, and according to what i read online, BOB has better snorkeling than MLE, and snorkeling is YMMV depending on location. Not every hotel has amazing snorkeling, but there are snorkeling tours that take you to amazing snorkeling spots.
(I'll be doing one of those today)
