We stayed at the Sealodge D7 for a week in June 2008. It was my wife and I, with our 9 year old daughter. We had just the right amount of room in D7, especially with the nice loft upstairs. The space for the 3 of us was not too cramped that we were walking all over eachother, and neither did I feel like I bought too much space. Great views of the ocean out out both bedrooms (loft and downstairs bedroom), as well as from the deck. This unit does have A/C and, although we used it, I'm not sure we absolutely needed it, although it certainly would have gotten stuffy if the wind would have let down. The A/C unit is out on the lanai (balcony), which takes up a lot of space, and, once it kicks on, it is not pleasant to remain on the balcony with the hot air blowing and the noise from the A/C unit. However, that is a very minor issue and you can always turn the unit off - if you travel in the summer time, I would prefer to stay with a unit having A/C just to not risk having a miserable time because of the heat. There really isn't enough room on this lanai to have a family meal. The kitchen was well stocked with dishes and the such, bathrooms were both very nice, plenty of beach items to borrow, and everything worked perfectly. The Sealodge, and this unit, have fantastic views of the ocean which are down below the lodge several hundred feet. I had many perfect mornings sitting on the lawn out front of the unit with a few cups of Kona coffee. There is also a path at the end of the property which winds through a forest, through a stream, alongside some dropoffs, and finally ends up on a very secluded beach. It's a picture perfect beach, has some great tide pools for exploring, very secluded, and, best of all, no driving required. However the hike is steep in some areas and the dropoffs along the rocks can be concerning for parents who have a small child with them, so check it out first to make sure your kiddos would be okay on it. The Princeville area is an excellent place to serve as a home base, with Hanalei Bay so close, and really great snorkelling at Tunnels and at the "end of the road". Surf Lessons in Hanalei Bay are great (very small surf in summer), primarily because it is a all sandy bottom so you don't have to worry about hitting rocks unlike most other beaches we visited on the Big Island. There is also a grocery store close by and, while expensive, is very convenient. D7 served us extremely well, and I could recommend to anyone with about 3 or 4 people. Also, the coordinator of this unit (who works for the owner) made everything extremely easy for us - she was prompt on communicating and responding to emails, providing us clear directions and the such... I never worried that something would go wrong that she wasn't prepared to handle (although nothing went wrong at all). Sometimes at these condos you are dealing directly with the owners who I think may be too busy to deal with clients the way we would like to be treated with such a large investment as your family's fun - this owner has set up a really good system with this coordinator (rest assured here). I didn't post any pictures of Sealodge itself, but some of the other reviews captured the essence inside and outside well, although much better in person. I'd say that although some of the exterior pictures of Sealodge might make you hesitate, it is really very nice and doesn't look "3rd rate" at all. This is not the 5 star luxury resort, but if you want a quite place to relax with a great view, with all the essentials, and reasonable rates, then I don't think you'll regret this choice at all. I'd stay at this unit again in a heartbeat.
