Has Amanpulo added pools to some of their Casitas? I don't remember ever seeing this before:

For some reason the reservation calendar isn't working for me (all dates come up as unavailable when you click through), but I could swear that the "Deluxe Hillside" and "Treetop Pool" categories are new ones.

Per Virtuoso website there are two of the Treetop Pool casitas.
