If you are talking about reserving through the email - I have used it during the times that I felt like it wasn't a busy time. Like when I've made reservations for Vero and Hilton Head during their off times. But, it might not be the best idea when trying to get the really busy time of year because they don't reply for a few days. I would worry that if you were booking a GV or BWV Standard View or needing a very specific date during a busy season - then you might want to use the phone and make sure you get what you want instead of waiting a few days while the email is processed. It's never happened to me, but many people on here speak of the need to call immediately at 9:00 a.m. to guarantee certain room types at special times of the year.
