We have stayed at the Hyatt OC many times and it is a great hotel! We are pretty picky about hotels and would not hesitate to stay there again. The rooms were fine before but now are very nice - they completed a huge renovation of the entire hotel (rooms, lobby, restaurants) about a year ago. It is right across the street from Target which is nice to stock up on bottled water, etc. The shuttle does run twice an hour and is very reliable. There is a full service Starbucks in the lobby which we love, and the restaurants are pretty good. As you've already noticed, the rooms are incredibly cheap! (Literally 1/4 the cost of the GCH last I checked.) Great service, good housekeeping, clean, just a really nice hotel. And if it is just you and your wife and you don't mind a little exercise you could walk to DL just fine - it's just a little over a mile down Harbor. Have fun!
