Picked this hotel after spending a couple of nights in Maui. The first hotel we stayed at was the Hilton Waikiki Beach and compared to that this was certainly more modern and "chic". My BF loved this place, especially the pool but for me it was a bit "too cool for school", with it's modern vibe which I felt was a bit out of place with Hawaii's laid back, beachy atmosphere.
Still can't really fault it for what it is - walkable distance to Ala Moana Shopping Centre, Morimoto's restaurant in house which was delicious, great service from everyone, the pool was nice and warm (although a bit too small for people who actually want to swim, it's more for lazing around and looking nice). Heard the club in this place is also really popular but was too exhausted to go.
If you like a really streamline modern design and are not too concerned about being far from Waikiki (I'd say about 10mins walk from the very end of the strip!), then stay here. If you're like me and prefer Hawaii more old school and down-to-earth, maybe skip it.
One more thing if you do stay here, it's walkable to the Ala Moana Beach Park which is a much nicer and less crowded beach than Waikiki!
