Is this a good one?

Against others of its kind
At $96 a day this sits a little under the $105 median for water & sailing. It is cheaper than 14 of the 24 water & sailing options mapped here.
Other things to learn in Thailand
6 other options in Thailand, starting with professional thai cuisine in Bangkok from $300.
When to go
Workable across 8 months of the year — Feb-Sep. Outside that the season is against you, not the school.

Most people give it 4 days, but the honest range is 3 to 7. The narrow spread means the course length is largely fixed.
