I've been trying different hotels in the OC area for a few months of trips lately and the ClubSport rolled around this time. The hotel was clean and the staff were friendly - so the basics were met. The room was sparsely decorated, but the bathroom was a bit odd: no towel racks and instead what looked like a book case in the corner used as towel storage. The shower was large and had a rainfall shower head - very nice. The focus here is definitely on the gym, as suggested in the name. I didn't have time to try it out on this trip, but it seemed huge and well-equipped. Ultimately what brought this hotel down from a 4 to a 3 was the lack of an executive / concierge lounge, although there is a nice breakfast buffet (free for Platinum members) to make up for it in the morning. Overall, probably a place I'd stay again with friends or family but would skip for a work trip.
