Travel Deals for the Week of Jan. 5

Here's this week's list of 10 travel deals. Many of these links lead to offers with a very limited shelf life, so if you're interested, act quickly. But don't act so quickly that you miss the fine print. For deals that aren't quite so fleeting, check out winter deals. Among the offers this week, a New York-Dublin one-way airfare of $161, a free night and a free day of skiing in Banff/Lake Louise, and a family package on the beach in Costa Rica.
