I wanted to let people know about my recent Mira Costa booking. Tonight I went online to make a 5 day reservation starting 6/28/2017. Right at 9:00pm eastern time I refreshed my browser. It took a full 2 minutes!!! There was only one room available for five nights and it wouldn't fit my family. I redid my search for the first three nights. I ended up with a Triple room on the Venice side. Like people have reported, my Visa card did not work. So I tried my Master Card debit card. This one didn't work either!! Fortunately my brother was online making his reservation too, and his master card debit card did work. Same bank, same card. How bizarre! Grrrr. He was nice enough to help me out and was able to book my room for me. Man is that site picky. A few bits of advice. Run a few test reservations in the days leading up to your actual date you need. I discovered that I needed to make a completely new account, and that I couldn't use Mozilla Firefox browser or my phone, but Chrome worked just fine. Went through many nights of frustration trying to figure this out. Hope this helps someone in the future. Good luck!
