I stayed 9 nights in PG/Sabang Beach back in May 2018 as a solo diver and first trip to PI. I just started looking at doing a similar trip for May/June 2024 and saw your thread.
When I went late May it was "shoulder season" so prices are less and
way less crowded.
El Galleon/Asia divers was a couple hundred yards down the shore from where I stayed (passed it going to town every day). I had quoted them, so had to check them out while I was there. They have a nice set up, but when most places were about empty, they still had mostly full boats so like being on a cattle car (if you are into that; fun with people you know, maybe not if solo. depends what you want/like). I stayed at Out of the Blue resort which was decent (to American standards) and had a pretty good restaurant. Got the pool view/Jacuzzi room so I could hang stuff on my balcony to dry ($108/nt). There were only a couple of other people staying there when I was there so also very quiet, had the pool to myself, etc. only downside was the kitchen had minimal staff and not all food was available. I ate at multiple places in Sabang including Atlantis, Papa Freds, Tamarind, etc. I've been going to Asia for the last 20 years for work (all over China, Korea, Taiwan, HK, Singapore, Malaysia, HK, etc) so I am used to it and like trying new foods.
I used Action Divers next door (associated with hotel) and had a great time. Wake up, shower, go upstairs for breakfast then down the stairs to the dive shop. Service was great as they cleaned and stored my gear and had my stuff set up for me every day (much better than my experiences in Cozumel). Probably 50% of my dives were just me and the Divemaster which was great! I got full bottom time and got to go where I wanted. Other dives maybe had experienced divers, and some not experienced divers (a couple of Chinese chicks with no buoyancy control kept the DM busy one time). I think I got about 28 dives in, including a day trip to Verde Island and a night dive. Definitely my best diving ever and why I want to go back. Except when I got attacked by a huge Titan Trigger by the giant clams (that scared the crap out of me, but I beat him back with my gopro rig
). Sabang Beach is great bang for your buck diving
Back then Air Juan ran a 12 passenger sea plane from Manila bay to PG (and other islands), and the hotel sent a small boat to pick me up at the sea plane dock. Super convenient, about a 30-40 min flight and was like $170 each way. Totally worth it as a time saver but it looks like they may not be in business now. So I am thinking a private van (~$100 I think)/public ferry ($10?) each way this time.
Tropicana Castle had best local exchange rates so I went there to convert a few hundred USD to pesos a couple of times.
Good luck with your trip.
