Finally booked Rangali 22nd August for 5 nights leaving 27th! Booked OW villa on points and looking at wiki we will probably be asking for sunset villas with shallow water around as we are not swimmers and hoping to snorkel just close by. Am I right that I should be asking for villas 315-330?
Yup.
I would love to try out the newly redecorated BV for the first 2 or 3 nights, just for convenience, the pool, being able to just walk directly to the beach easily. Any recommendations?
You mean the proximity to the main pool, right? And there are some posts in the wiki about BV selection too.
