As a former Timeshare owner at Pelican, which is now Simpson Bay Resort, I can vouch for SBR and The Villas. We gave up our time there when they were refinishing everything and the MF’s got out of hand.
As Pat mentioned Royal Islander Club La Plage is very nice. We exchanged into there a few years ago and enjoyed it. There is a lot to do and many dinner choices right there in Maho without having to drive.
We extended a stay 2 nights many years ago and stayed at La Vista. The room was very nice. Have never been in La Vista Beach but have heard good things.
I always hate to make recommendations because no 2 couples are alike, but if it was my choice I would take Royal Islander.

Good Luck, enjoy and let us know what you decide, and don’t forget a Trip Report!
