First, the most important things to know about the Tabon Caves:
1. There is a small museum (maybe 15 minutes worth of attractions) in Quezon but the more entertaining part is the actual caves. It literally has about 50 feet of exhibits. The admission is small, maybe 10-15 pesos, but the boat is considerably more.
2. If you go on your own (without a hotel setting up the tour), note you have to get a permit to at the museum before going to the caves. They recommend calling ahead so the museum can schedule a boat. We did not know this and we almost did not get a boat because the fisherman had already gone out for the day and were tired.
3. The boat ride to the cave is an adventure...similar to other water tours (Honda Bay or trip to the underground river) you might take in Palawan. At the caves, there is a small wharf that leads to a sandy area with about 1000 square feet of beach. The entrance to the caves is there, and you have to walk up a fairly steep slope to get to the first cave.
4. Some of the steps are quite steep along an embankment that can give you a little vertigo if you aren't good with heights.
The last two points are key. This is not like the underground river....it is a hike. We had 14 people in our party, including 5 kids. We lost 7 of them at the second cave, three more at the fifth cave, and one gave up half way through the 7th. In the end two adults, and two kids (one being carried) made it through the whole tour.
Our party was not in the best shape...physically fit hikers are going to have no troubles with the walk. But it probably isn't the best for elderly folks (due to the strenuous climb) or young kids (due to the steep sides).
The most interesting part of the walk for us was the land crab and frog we saw on trail and the bat we saw in the caves. The caves were not particularly impressive (similar to other spelunking), and there were no cave drawings or anything of that sort. There was not a lot of standing water like the caves in Sagada.
We tried to have a meal on the wharf, where there is a table. But there were only a few places to sit. The kids had a lot of fun in the water which is shallow, clear, and sandy. It isn't really a beach, but that part was fun, so we'd recommend bringing swim suits.
Note there is no restroom, no water or other supplies, no elevator, etc.
We were staying in Narra at the time (which is about 2.5 hours from Puerto Princessa depending on road construction going on). It took about 2.5 hours to get to Quezon, but our driver thought that was faster than usual.
