There's no need to shelve that summer vacation you wanted to take but never got around to planning: The last two weeks of August may be the most popular time to get away for the season, but there are still plenty of options available for travelers who are game for a last-minute escape.

Jack Ezon, president of travel company Ovation Vacations, said that July is actually an opportune time to book a late August trip. "Room cancellations in coveted places like the Mediterranean happen in July just before hotels impose cancellation fees, cities in Europe are quiet, and many resorts all over the United States have space, especially if you're willing to go midweek," he said. "Africa, South America and Canada are possibilities, too." Here are a few options for a memorable summer vacation that you can plan right now.

Explore Argentina

Luxury travel company Royal Travels & Tours is offering a private seven-night trip to Argentina that includes three nights in Buenos Aires with a city tour, tango lesson and museum tours; two nights in Salta, in the northwest, with a city tour, a winery visit and tasting and a cooking lesson; and two nights in Iguazu Falls with hiking and whitewater rafting excursions. Stays are at upscale hotels throughout, and breakfast is included in the cost. Prices start at $1,900 a person. Because the tours (and the agency) are private, you will need an agent to set up the trip. E-mail travel agent Ben Adams directly at

London Calling

Maybourne Hotel Group, a collection of three high-end properties in London, including the Berkeley, Claridge's and the Connaught, has an offer in August where guests who book a four-night stay enjoy one of those nights for free.

Those booking with a travel agent who's part of a luxury travel network such as Signature Travel Network or Virtuoso also get a space available upgrade, breakfast and a food and beverage credit. Prices per night (before the free night) start at 425 to 500 pounds (about $550 to $650).

An island getaway in Maryland

The Inn at Perry Cabin by Belmond in charming St. Michaels, Md., has a "Skip the Bridge" package available for late August.
