On February 7-10, 2019, myself and nine other friends travelled to Killington Ski Resort in Killington, VT.   The conditions were about as bad as you could possibly have on the east coast - rain and warm during the day and sharp cold drop offs at night which makes it terrible for skiing the next day - everything is frozen and crusty.  Ticket prices at the mountain were $95 a day, but if you look on eBay before your trip you can find some deals.  I got two tickets for $140 each.  Hoping next year the conditions are better!
