Best Ways to Save on Summer Vacation

With school letting out and sultry summer days ahead, it's time to start thinking vacation.

Because it's a supply-and-demand world, you'll likely be up against higher airfare, hotel costs and car rental rates. But here are some tips to help keep things affordable.

If by air ...

If you plan to fly domestically, your best chance to score cheaper fares is by booking about 60 days in advance. For international travel, make it 90 days. This may also be the right time to cash in frequent-flier miles or companion fare coupons. Comparison websites such as KayakOpens a new window, SkiplaggedOpens a new window and AirfarewatchdogOpens a new window can turn up cheap airfare.

If by land ...

Make sure your vehicle is in good running condition. The last thing you want is a blown engine in a one-mechanic town. Depending on your route and time constraints, Amtrak or Greyhound may be affordable alternatives. Renting an RV may also pencil out, particularly with relatively low fuel prices.

Consider visiting places during their off-seasons

After major league baseball teams break spring training camps in Arizona and Florida at the end of March and it really starts to heat up, airfare and room rates tend to drop dramatically beginning in mid-April and lasting through the summer. You can find high-end hotels with luxurious swimming pools to keep the kids happy for hours. Just remember to get in your golf, tennis and hikes before midday.

Accommodations

This can be a touchy subject because comfort levels are highly personal. If you're traveling solo to a metro area and don't mind roughing it, check out CouchsurfingOpens a new window. Priceline claims to save up to 60% over published hotel prices. You won't learn where you're staying until your bid is accepted, but you name the price, and you can make another offer if your initial one is rejected.

Home-swapping companies operate domestically and internationally. Most often you arrange to exchange homes simultaneously, but in some cases you can stagger swaps to accommodate travel dates. There are fees to join home-exchange services, but typically they are more than offset by savings from avoided hotel costs. Sites to check include Love Home SwapOpens a new window, KnokOpens a new window, HomeLink, HomeExchangeOpens a new window and IntervacOpens a new window. You may also be able to exchange vehicles.

The great outdoors

And if you really want to save ...
