Almost everything on the island is priced per session, with a discount for a block of five or ten. A block is cheaper per hour but ties you to one teacher, so take a single trial session first and only commit once you know the style suits you.

A standard private session runs sixty to ninety minutes. Group classes run longer and cost less per head, but the pace is set by the group — which is fine for yoga or surf, and rarely fine for exam preparation.

Two things decide whether a block is worth it: whether unused sessions expire, and what happens when the teacher cancels. Both should be stated before you pay, and a teacher who will not put them in writing is telling you something.
