I suspect if they only started looking into how to price the rooms recently, they may not have good data yet. Many hotels in this part of OC have wildly distorted room pricing during OC Fair season, and pricing suddenly comes back to normal the moment the OC Fair ends in mid-August. (That pricing can domino far up past Anaheim, even!) So it's a hard time for a new hotel to just look at what other hotels nearby are charging and set rates on that. And within the Marriott family, they only have other types of brands nearby, like the Springhill Suites two exits down on the 55, to look at, but Springhill is a bit different than Residence, and is also closer to the airport, so I'm not sure how useful even that is to them.
And the Dyer Road exit hotels are all over the place, a mix of hotels normally around the $80ish rate next door to hotels normally around the $150ish rate. Should a new Fairfield price like the La Quinta or like the converted-from-Radisson (and still showing it) Hampton Inn, when there's no similarly between the rates at the two? Should a new Residence price like a Quality Suites or an Embassy Suites, when there's no similar between the rates at the two?
Or should they look to prices in Anaheim (which is the closest they can find the same brands)? But Tustin is not quite Anaheim!
