Definitely make sure you recheck those day pass prices. That's the price for a normal day, i.e. non-wedding day. Usually if you're having a private event on the property and they're there for your wedding, it could be that you don't have to pay for them at all. After all, you've already paid per head for them to attend your private reception. Karisma policies change frequently, but the last I heard this was the case.
