Looking for an affordable and unforgettable winter family getaway idea? Heed no. 10 in our recession travel rules  and discover our parks systems. Wintertime in Utah's Zion National Park is a wonderful season, when crowds thin out and you can enjoy less congested hiking and horseback riding on 200 miles of trails surrounded by spectacular 2000-foot canyon walls. Normally a room at the in-park Zion Lodge starts at about $153 a night, but if you visit between December 1 and March 15, 2009, you can take advantage of a winter promotion that lowers the nightly rate to just $80 on weekdays and $95 on weekends. You can book online or call 888/297-2757 and be sure to mention code WNTR. Note: The rate increases to $105 a night during the holidays (December 23-30 and February 13-15, 2009) and New Year's Eve is a blackout date.
