Presale sessions can help everyone plan
Like movie tickets or concert tickets your skatepark can pre-sell tickets to sessions you sell, online or in the store. Showing people that there are limited numbers of session entrances can also help sell more sessions ahead of time. So if you have a lot of people coming in groups from out of town and they know their schedule, you can ensure these people that they will be able to get in and have the trip they were planning. Similarly if skaters and bikers see that a session is almost selling out, they can elect to come at another time rather than trying to pack in to a crowded session. Having a website that enables session sale and provide data in real-time can also help you plan on staffing needs. By seeing that there are a lot of sales on afternoon sessions or on weekdays, you can staff the appropriate number of people to make sure that everyone is having fun, and all areas have enough people to keep lines down. An additional benefit of adding online sales is that people won't show up despite having paid, or they will have bought too many tickets and will absorb the cost for a variety of reasons. After your stated "no refunds after this date/time" it is reasonable to assume that giving a refund could have turned away others who would have paid, thereby losing you money. While you could give a rain-check, this could be a way to increase sales and keep a steady flow of capital into your business even on non-weekend/busy time periods. Adding functionality like this could go hand-in-hand with having a mobile ready and truly interactive site will help you and your customers get the information they need, to make their visit better.
