Poster above summed it up, if you think it'll be your only trip to R4 maybe a LoB is worthwhile, on the other hand I still think resort diving is better for the appropriate selection and timing for local spots since there can be loads of divers sometimes and you may easily skip/choose the sites according to the number of boats around, as there is no fixed itinerary.
While your choice of LoB might be limited by the spaces available for 2024, here are humpteen dive resorts open now so it might be difficult to select an option, some ideas :
- I wouldn't recommend Raja Ampat Dive Lodge anymore, as much as I appreciated it in the past (lesser divers) feedback from one of my friends last year was that it has really gone down.
- Papua Explorers is a solid dive resort turkish owned, hosting underwater photography workshops, you shouldn't be dissapointed .
- Although they were the original Max Ammer's resorts I find Sorido much too expensive while it's americans favorite resort, its sister Kri Eco is a scam they won't operate boatdives on saturdays
- Raja4divers is one of the best loved resorts in terms of service (Swiss management).
- I'm going soon to Cove Eco resort, french owned and next to R4D, which was highly recommended to me by one of my friends. Completely under the radar but interesting location in the NW part of Dampier.
- Misool Eco Resort is the only one far off South of Raja Ampat, expensive : sell a kidney first.
- Not sure Papua Paradise would be typical of R4 diving : located south close to Batanta where dives are more macro than the usual fare.
As for cultural or landtrips, you can already do some bird of paradise trips (usually on Batanta) while you're there but don't expect much from mainland Sorong.
If you want to take a few days and go sightseeing, depending on the time of the year , Bali is an option like many posters said though not very practical with flights, You'll have to take 2 different flights to get there.
I can give you another landtrip idea if you have 3-4 days left : you may fly to Makassar/South Sulawesi and get a tourdriver to Rantepao to see the most interesting and unique Torajan culture in Indonesia.
Very friendly people who will greet you in their villages, skilful woodden houses architects, pretty rice fields treks in the mountainside, the only problem might be the weather depending on the month of you visit it can be rainy up there, takes more than a half day drive (5-6h) to get to Rantepao from Makassar .
