European Destinations (tel. 877/267-2247; pairs the best of Paris and Prague with this six-night package for fall travel, from $1,135 with airfare.

Spend three nights in Paris at the budget-friendly Saint Louis Bastille, a three-star property close to a Metro station, the Opera Bastille, and within a short walk to the lively Marais neighborhood. In Prague, you'll stay three nights at the four-star Plaza Alta Hotel, on the outskirts of the city center but close to a metro station and tram stop for easy access to the major sites. With dozens of hotels to choose from in each city, you can certainly upgrade to a property that's closer to the attractions.

If you want to travel sooner than the fall, you can. Just expect the price to rise or drop accordingly. European Destinations shows a two-week price history for its trips, so you can easily see which destinations cost less and which travel dates are most advantageous for travelers, and so forth. It's very helpful if you want to customize this package.

How much does this package save you?
