As an alternative in Anilao, consider Crystal Blue as already mentioned. Mike Bartick is either an partial owner or in the management chain (or both). He's a well known pro photog and has a lot of influence on how the place is run. It's really set up for UW photogs. One of the best camera rooms I have ever seen.
Four (or fewer) divers to a boat with a guide. And the guides are excellent.
Mike does periodic dedicated photo trips/classes and is an excellent instructor if that works with your schedule.
The only downside is that the only spaces that are air-conditioned are the guest rooms and the camera room, if that makes any difference to you. Not sure it that's the standard in that area as I have not stayed anywhere else in Anilao.
Have only been there in April/May timeframe and conditions have been excellent.
PM if you want more info.
