Go obsessive compulsive and you'll never miss a flight.. Or a parking place, or the right restaurant with accompanying coupon.

People in my household have the OCD gene. It comes in handy when traveling. Everyone has hand Sanitizer, dental floss, aspirin, and coupons.

That's the up side. The downside is, it takes 30 minutes to choose yogurt cartons that will fit snugly into the hotel refrigerator. We must check calories and fat content.
Then there's the mathematical countdown to leaving. How many oranges must we eat per day? Bottles of tea? Pieces of Key Lime pie? Did we save enough clean underwear? Are we on budget?
Now we need to scope all the competing hotels so we know where to stay next time. We definitely know we got the best deal, shadiest beach. (Hilton, Key Largo) we've located the most gorgeous sunset--Sundowner's Club. Although some say Mallory Square in Key West. I won't quibble.
Now, if a shady beach is not what you wanted, there's plenty of sun, too. I just like sitting under tropical trees all day without getting burnt as I gaze at cool, blue water.
