Prelude to Cancun

After years of Ken saying he wanted to go to Cancun--we are actually going! I'm excited, and yet, I really hate packing. Trying to decide what we will need for a week and keeping it to one 50 lb suitcase and 1 carry-on bag isn't always an easy task. I tend to think in the "what if I need this" zone. Then when I get back home, I find that I didn't really need it all--but then who knew? I mean--should I take a towel? They should have them at the hotel--right? What about a hair dryer? All hotels have them now--right? But even in Mexico? Will we need an electric converter? Is it safe to plug electronic things in it? I'll let you know when I get back.
