I went to Guadalupe on the Nautilus Explorer in September 2015. Overall, it was excellent.

Food: We had all types of food allergies on our trip (gluten, dairy, eggs, etc.) and everyone was well accommodated, and the chef paid very close attention to cross contamination. The food consisted of a continental breakfast, full cooked breakfast, lunch, dinner, and snacks. Everything was delicious and there was plenty available. It was some of the best food I've had on a liveaboard.

Cabins: I like the fact that the double cabins are side by side beds, not bunks. There's plenty of storage space. By comparison to most other liveaboards, the cabin are a decent size. The shower always had hot water and strong water pressure. The toilet was a real toilet (like you'd find in your house), not a marine toilet. The only complaint I have about the cabins (and why I gave it 4 stars instead of 5) is because the mattresses are really hard. However, I was told that you can ask them to put a comforter between the fitted sheet and the mattress, which would help.

Crew: Stellar. Every one of them. The hostesses are always around to bring you a drink, snack, or whatever you need. The crew will bend over backwards to ensure you have an amazing trip.

Diving: Great white sharks - what's not to love?!? Nautilus Explorer runs an on-time and efficient dive schedule for the submersible cages. The guys on deck are always available to help you don weights or get in/out of the surface cages.

Overall, I was very impressed with this boat and I'm already scheduled to go on Nautilus Explorer again next year.

I was on the Fiji Siren in Feb. 2014 and loved it! The Nai'a is also an excellent choice but there are some differences between the two, and I think I would give Siren the slight edge, though my reasons for doing so may be different from what you're looking for.

Cabins: The cabins on the Fiji Siren are really nice and have more floor space than most liveaboards I've been on. I really like the wood floors vs. having carpet which inevitably ends up smelling like mildew. The mattresses are comfortable, and the bathrooms are nice as well. The only complaint I have is because it's all wood, it sounds creaky at night.

Food: Yum! I have a pretty restrictive food allergy, and it was well catered to. All the ingredients seemed very fresh. Fiji Siren offers all meals buffet style, which I prefer because it means you can have as much or as little as you want, and can eat it in the order in which you prefer, instead of waiting for individual courses to come out.

The Boat: This is where I really prefer the Siren to the alternatives. The Siren has a wonderful outdoor dining area with really nice lighting above. The indoor lounge is very spacious, and each guest has personal drawers for storage, not only in the galley but also on the dive deck. Speaking of, each guest has their own dive area with their tank, gear, and a few drawers to store stuff like hats, sunglasses, etc. It's a well laid-out boat with nice lighting, and it feels warm and cozy.

Guides and diving - Awesome!

Fiji is one of my favorite places to dive, and I'd recommend the Siren without hesitation!

I stayed here in March 2016 and had a lovely time. The bungalows are absolutely gorgeous. The only downside (for some people) is that they don't have AC. However, I never felt like I needed it with the night breeze, and mosquitos didn't seem to be an issue in the room, especially with the mosquito net.

The food was buffet style, tasty, and plentiful.

The dive op was excellent. The only downside is that Papua Paradise is located a bit farther from the best dive sites of the Dampier Strait. The boats can still go there, but you're more likely to dive the sites around Papua Paradise, which are still excellent! And they will go up to the other sites, it's just a longer boat ride.

A huge benefit to staying here is, unlike the other resorts, Papua Paradise offers transfers to and from Sorong every day of the week.

I really enjoyed staying here and wouldn't hesitate to go back.
