Sweethearts night

Hi! A group of friends and I are going to our first Disney after dark event for sweethearts night and we have no clue what to expect, I just decided to buy them for everyone since we were already going to be there that day. I’m just curious about things like are all the rides open or just some? Is there anything included in this excessive amount of money spent or no? We’re excited just going in blind haha. Thank you!
