Replying to Recomendations? (I am a NOOB!)

okay so FINALLY my parents have agreed to take a ski trip next spring break. They said I could pick anywhere I wanted to go. I want to either go to Mammoth or Lake Tahoe (N*, Squaw, and Alpine Meadows). This trip would be the first week in April. Just based on average snowfall and terrain (park and steeps) where would you go? Oh and I'm from Wisconsin so pretty much seeing a mountain would make me shit myself, the biggest i've ever skied is 400 vertical feet and the most pow is 6 inches over a groomed run. Any help would be very much apreciated. Thanks.
