You can join the waitlist for Baja Beach Fest here. Click on the weekend you'd prefer to attend and then "Request Passes." Select the number of passes you want. The price you are shown is the price you will be charged if your request is able to be completed. Then, simply enter your card information and complete the process. You'll receive a confirmation email from Lyte letting you know that they received your request.
Please note that submitting a request does not guarantee a pass. The number of passes returned by other fans determines how many requests can be completed.
If you do not mind which weekend you attend, you can select the Either Weekend, which will put you in a separate line for the first available passes for either weekend. If you select this option, you are willing to receive passes for either weekend.
