Response to CP
It's sounds to me like you haven't been to that side of the island for a while. I certainly agree that it is quieter & more laid back than SMB but a lot of us prefer it that way.
Barefoot plays in our bar/restaurant twice a week and Morritt's usually has live entertainment on different nights and if we want more night life SMB is only a 35 minute drive. Everybody is different and it really comes down to personal preference.
With regard to the big "M" the eastside has a gentle breeze blowing pretty well constantly I have seldom seen any mosquitoes and we actually sleep with our patio door wide open whereas you generally couldn't do that on SMB or the north side.
We were actually up at Rum Point (only a 15 min drive from us)twice about 3 weeks ago (had friends visiting from Aus) and one day we got lots of bites and the next time (only a couple of days later they were going to Stingray City) we were there for about 3 hours and didn't get one so it seems to be intermittent.
