What’s The Biggest Thing Ruining Your Vacation

It's still Summer, but basically right before Back to School.  I see a lot of people trying to get in the last vacation before that craziness starts.  Family vacations.  Generally we all hope for good weather, healthy kids...and adults, short lines, and a great time had by all.  But what is the main thing that would ruin your vacation?

There was a survey taken... and the number one thing was... lost luggage.  I have not had that happen to me...yet.  But I'm always freaked out that it's going to, so in my carry on I always have some sort of an easy change of clothes, and also a swim suit if we are going somewhere warm.  At least then, I'll have something to do while waiting for my luggage to catch up with me.  God forbid that ever happens, but I'm superstitious about it.  I figure if I don't plan for it, it will happen.

The others that came up in the survey that would be a vacation disaster were no internet- 49% of people said that would ruin their vacation.  Good grief!  I feel like that might be a blessing.  Forced to unplug  Others were food poisoning, bad weather, a lost credit card, no air conditioning (that would suck) and a lost reservation.
