For hostel reservation, email dolphinbay@btl.net if it is for resv after August.
If it is for the month of Aug., I wont be checking that email so instead email belizeanthings@yahoo.com (my sister) to tell her your dive plan (how many dives, what spots) and she can prearrange all these for you through her travel/dive/tour agency.
Kind Regards,
Tinas Hostel
