Hopefully there will be a replacement (Hyatt Regency or higher) in the area to support SNA and businesses/trade in the area. LAX has NOT seen HR for 10+ years, after it re-branded.
Hyatt Regency Alicante/Orange County/Garden Grove is too far, and barely passes HR standards IMO. HR Newport Beach is trying, and does have shuttle service to support SNA, but no club.
