confused? Minnie and friends dining or just h&v dinner..

Hello everyone, I booked a fantasmic dinner reservation for a night in April, and it gave me a 6:15 reservation and H&V. I thought this was disney jr character meal and realized afterward that that's only breakfast and lunch. I was going to change it but then I saw that there is a special minnie and friends party from march-june there at night. It's more expensive but looks great, am I reserved for that? is it every night march -june there or would I have had to make a special reservation.. I'm hoping it's minnie and friends, any help appreciated, thanks!
