The next one is coming up February 5-11 and will feature plenty of family activities for everyone including scavenger hunts, relay races, bands, karaoke, movie nights, turbo tubing and special visits from SpongeBob Squarepants and Dora the Explorer. Of course, Sunday River's awesome skiing and riding is part of it too. And families booking a 3 to 5 nights at the resort February 4th to the 8th will get free skiing for kids and teens ages 6 to 18.
