Though it may seem appealing to sleep through those long waits on the tarmac, avoid the temptation to take a sleep aid until you're up in the air.

You may miss important announcements, or, worse yet, you may be asked to disembark and wait for a later plane.

If you plan to take a sleep aid, be sure to take a seat where you are less likely to block in other passengers, like a window seat or a middle seat. Your fellow passengers don't want to climb over your dead weight in the middle of the night.

Before departing for a foreign country, be aware of any national holidays that will occur during your trip. Do your best to learn about even the minor ones that aren't widely known.

My husband and I nearly had our honeymoon derailed by a national holiday during our stay in French Polynesia. Most businesses were closed, including restaurants, banks and museums.

We were saved by the tourism office, which offered us a chance to spend the day learning about Tahitian culture on the grounds of a closed museum. Otherwise, we would have wasted an entire day of our trip stuck in an urban area with nothing to do.
