interesting comparison of sri panwa and trisara, IIRC the reviews so far on FT have typically been more critical of trisara.

rate comparison (with no bearing for OP, but for comparison purposes)

Trisara
1BR oceanview pool suite $556
1BR oceanview pool villa $780
1BR oceanfront pool villa $1110
2BR oceanview pool villa $1080
2BR oceanfront pool villa $1365

Sri Panwa
1BR oceanview pool villa $1050
2BR oceanview pool villa $1400

Amanpuri

oh, all Trisara's have pools.. though i seem to recall the suites were said to be very small.
