Lately, the lady said that not all people were receiving email confirmations for some reason. I would write down the time you made it and just tell her when you pull up to the gate. You won't be denied.
The problem has mainly been with the email companies. The reservation system uses an email service that came with the package. If you are using @AOL.COM you have a very slim chance that you will ever get a confirmation email. They are blocking most of the addresses that the email server uses. Because others use the same service it seems that it may be impossible to get this unblocked. Someone has said that @ATT.NET is also blocking but I have not been able to confirm that. So far those with Gmail accounts have had fewest problems. Some emails are being caught in local spam filters or promotions and such. Please do not make multiple reservations for same day. If your got to the new screen that said "Squaw Creek Fishing Reservations- Thank You" it is there. The only problem would be is you can not cancel it yourself. You would have to call or email the park to do it
