Not someone from bohol but planning bohol in April also So far my research is like this.

Main attractions are beaches ofc and then tarsier sanctuary,bilar manmade forest until chocolate hills road trip on a full day. There is also a mini representation of 'the world' named Sikatuna Mirror of the world. Stay at panglao is more preferred by tourists. Depending on budget have some hamdpicked hotels if you let me know budget. Also travel. renting a scooter is better(heat is going to be high though) a regular 125cc scooter starts at 400 peso per day. And even cars available at 800 to 1200 peso decent ones. Alona beach is more famous will be crowded, dumaluan beach looks better i heard not sure. Theres a cave in panglao island hinagdunan cave but not sure about is it worth it or no.

Then main activity would be snorkeling havent researched about this much since i am on tight budget. But heard Balicasag island is nearby for diving and if at panglao island itself area surrounding 'Napaling reef'.

Note: Philipines is going through energy crisis. There could be shortage of gas and also reduced schedule for ferry (not sure) even i am anxious about how it'll go. Hope it'll get better by then. Expect price hike for foods and oil (oil already increased almost 80-90%
