Put in that vacation request! The sooner you can take off, the more you'll save during Intrepid Travel's one-day sale, June 30 from 10:30 a.m. to 7:30 p.m. ET.

Select July departures are reduced by 60 percent, while those in August are 30 percent off, and any other Intrepid package for travel through December 31, 2009, is 15 percent off. Pull up their website or get ready to call 800/970-7299 and supply the booking code 3132. Procrastinators will likely be disappointed as some of these trips have only four spots left.

A seven-night tour of Egypt in July covers the Sphinx, the Pyramids of Giza, the Valley of the Kings, and a Nile cruise on a felucca for $310 instead of $775. An eight-night Peru package, including the ruins of Machu Picchu, is down to $664 from $1,600, and a sweeping 15-night trip through Italy, Greece, and Turkey is $910 instead of $2,275. All prices are per person.

As we've previously noted, Intrepid is friendly to solo travelers and pairs an individual with a roommate instead of charging a single supplement.

Some fine print: The discounts don't apply to Intrepid Travel's additional local payments, typically a few hundred dollars that are due on arrival and go toward incidental expenses and local guides. For instance, the Peru package comes out to $964 per person: $664 (sale price) plus a local payment of $300. Also be prepared to pay in full for trips booked at 60 or 30 percent off.

If you can't act fast enough for this one-day sale, bookmark Intrepid Travel's promotions page; trips departing within three months are regularly listed at 20 percent off.
