My partner and I had the pleasure of staying here for a few nights while in Waikiki and found it to be a great hotel. The room was spacious, comfortable and situated very near the main shopping strip and beach.
The room was a tad dated but this is not something that I feel impacted the enjoyment of our stay at all. The staff were very welcoming and helpful, particularly when we needed help getting to Pearl Harbor the following morning.
As a whole I would definitely recommend the Shoreline to anyone needing a decent, well priced hotel in Waikiki.
