$20 bucks sure is cheap and concur on WestPort Cottages.......
maybe Tropical Fantasy too....across from the Boat Bar.....
JahB's is about $30 a night but the cottages have their own bathroom plus a refrig.......Westport doesn't have those
Secrets at Firefly have been known to go as low as $20 a night too.........their prices are all over the place.....
Miss Mary's is probably around $30 a night on da beach........beside Barry's.......location location.......not far from roundabout either
couple other people rent a room in the same alley as Miss Mary's too........
too bad you didn't take time out last reach to look.......
mi make it a point every reach to check out at least one place for future stays........
you'll find sumthin......maybe just book a room for the night like at Westport and then go check out things when you arrive?
