All goodies in trunk of the rental car, with the inside trunk release disabled or locked-out if possible.

Renter's or homeowners insurance with a coverage for personal items stolen while traveling.

Traveler's checks for large amounts of money.

If you must leave items at the hotel, place a "do not disturb" sign on the door so that housekeeping stays out. Also, might consider carrying your valuable items disguised in something everyday like a cooler.

I never use the hotel safes -- if you are at a hotel that has a safe in the room, that's the first clue that you might become a victim. I'd seek lodging elsewhere. And I never leave valuables with the front desk for storage in their safe.

The fewer eyes that see your stuff are the fewer people who might considering taking it.

Oh boy I am rambling on here. The "Yelpie" looks like a neat product, but I'll buy a $5 cooler and keep the other $70. <img src="/images/graemlins/smile.gif" alt="" />

A small Otter-box or Pelican case buried in the ice at the bottom of the cooler (or in the sand under the cooler) has always worked for me at the beach. Of course, I usually only have water or Gatorade, so the cooler (and contents) are not as likely to be stolen as a cooler full of beer.

This works well in a hotel as well. If we are traveling by car, we'll usually have a cooler for water/soda that we'll bring into the hotel room. Of course, we always just leave the Do Not Disturb sign up as well.

Portable safes.....something for the criminal to crack at his own leisure. Concept has been around and seemed silly until I see this one with an alarm. Personally, I keep people from knowing what valuables I have and keep it well hidden and it has always worked when outdoors.
