Republ1c Wakepark Q

Has anyone been to Republ1c Wakepark in Nuvali? Been trying to contact them but the tel. no. in the website doesn't work. Tried emailing but no reply yet. We'd like to try it out and am wondering if anyone can give tips such as:

1. Do you need to reserve?
2. Do they accept walk-ins?
3. What's the procedure for beginners?
4. Locker facilities?
5. Other helpful comments and suggestions.

Thanks.
