Europe -- specifically Portugal -- is more affordable than you think with this deal from Gate 1 Travel (tel. 800/682-3333; to Lisbon, which includes airfare and four nights from $899 for travel this winter.

If you're wondering about the weather in Lisbon in the winter months when this package is valid, the average temperatures range in the mid to upper 50s -- certainly a lot warmer than a good chunk of North America at this time of year.

With this package, you'll spend four nights at the Sana Executive Hotel, a tourist-class property outside the city center in the new commercial district. The hotel is a five-minute walk from a Metro stop that will get you to the city center.

Why is this a deal? Booking airfare alone starts at $851 from New York City with one stop, according to a search for Dec. 14 departures. In terms of hotel rates, the early booking rate for the first available departure in December totals €185.60, or $274.87 (or about $66 per night), including taxes based on double occupancy. If you booked airfare and hotel independently, the total price would be about $1,095 with taxes and fees. This package starts at $899 and once you factor in at least $107 in fees, it comes to $1,006 -- which means booking this Lisbon package would save you about $90.
