Four of us decided to spend part of the holidays in Bohol. Sister was lucky to have scored discounted tickets from PAL even if she only booked 3 days before travel date.
Observations, lessons learned, tips:
1. Countryside tour - I contacted Ritchie Vasquez whose contact numbers i found in two other blogs. But upon reaching the airport, Ritchie told us his brother Rejjy will be the one to drive for us. For Php2000, they have 7 sites as part of the tour package.
Tip#1: Later in the tour, we also met two other enterprising guys who were driving for balikbayans. These two guys were much more enthusiastic and younger, so I guess they'd be more fun (Rejjy was a bit stoic) to have as tour guides. Joseph Bungabong, Mobile +63910 818 6880. (i'm not paid for this, just offering an alternative :) )
Tip#2: Confirm the sites included in the package you're getting and include a fetch from airport/bring to hotel arrangement.
2. Chocolate Hills is the farthest site so it was first in the itinerary said driver Rejjy. We already noticed that skies were a bit cloudy on the way but we really didn't know the implication of it. Here's the implication:

Yep, we didn't see the famed Chocolate Hills because of thick fog :). Oh well.
Entrance fee: Can't recall if it's Php150 or Php50/person
Tip#1: Check the weather. If it's cloudy or rainy, go to other places first before going to Chocolate Hills.
3. Hanging Bridge of Sevilla - For Php10, you can cross this bridge (or just a fourth of the way) and have your friend take your pic. I saw locals crossing the bridge carrying stuff from the market. Hope they generate the funds to build a better bridge for the locals.
4. Tarsier - We disturbed their afternoon nap. Poor fellas.I don't recall the name of the place. They don't charge a fee but donations are welcome.
5. Loboc River Cruise - We went for Riverwatch. Food was ok. Food is Php300/person and government tax is an additional Php100/person.
Tip #1: Be there around 11:30 to catch the lunch crowd. Boats wait a while for more customers before leaving the docking station.
Tip#2: We treated our driver to the river cruise lunch. But there are also cafes/restaurants in the docking station.
6. Osang's broas - The bakery is behind Baclayon church. There is another bakery beside it which was newly constructed. Good thing i read about Osang's being old school and marked by a pile of firewood. Just go past the new bakery and you'll find Osang's. They sell broas packs for Php50 and Php100. The 100-peso pack was quite a lot. I think they're good pasalubongs.
We finished the tour around 3pm and Rejjy brought us to Bohol Bee Farm. If you want to go to sites not on their list, you'd just have to pay extra (Rejjy said Php300 for Hinagdanan Cave).
