Replying to Best Spring Break Skiing?

Well, my mountains closing this weekend and I convinced my dad to take me skiing over break. Its i think the week of the 14th. I was thinking sunday river because we've went to killington so much but I need some input. I ski park, i guess intermediate for my second year skiing park and my dad just likes groommed trails (ie Great Northern / Eastern at KTon). Any suggestions for a place with a great park and good all mountain trails like killington?
