Hi Jeannie, I just returned from a stay at Hyatt Newporter from 3/28 through 4/2. We got this on priceline.com for 29.00/night. There are about 5 separate areas of rooms--main building, building surrounding main pool, villas, Lido and Balboa buildings (each with their own pools and hottubs). The grounds are beautiful, the people are very nice, on-site restaurant was OK, small gift shop, express sandwich/coffee shop, and sports bar. They have complimentary shuttle to Fashion Island Mall and Balboa Island. We didn't use the shuttle since we had a rental car. It only took us about 10 minutes to get to the beach by driving and we had a great time. The Balboa Fun Zone was awesome for the kids. We also did some whale watching from here. The rooms were fine. I've stayed in better so I wouldn't call them luxury--they were just rooms but not dirty. As for inside or outside hallways, there are both. Balboa has inside hallways, Lido has outside. They look like a motel door near the pool but on the other side of your room is a sliding glass door (we had a golf course view).
The only negative I would have about this property is that the self parking is quite far. I was not looking forward to it after returning from DL. Enjoy yourself!
