I still have not received a confirmation email. Some others have said they have slowly been getting them. I have been wondering whether to call as well.
Oh ok, I guess not the exact same. It lets me book for the 15th. It shows my other dates highlighted in blue on the calendar but I can't seem to book any of them except the 15th.
I am in the same boat as you. I was on right at 6am and it won't let me book anything after 7/15. It shows me the dates available, but when I click on an open time I get the lady and tramp error screen. I am staying onsite.
