Vacation time again

So we all know it's almost that time of year again. Time to dig out the swimsuits (and hope we fit in them) and go somewhere fun! I am having a terrible time figuring out where to go this year. I had just about settled on Dallas/Ft. Worth, TX area because there are so many things to do. Now I can't seem to make up my mind. Plus this will be the first time my son and I have gone on vacation by ourselves. Usually we go with friends or my sister and her family. It's a little scary. I hate driving in big cities. *sigh* Anyone out there actually read this and have any ideas for a kid-friendly (and mom-friendly) vacations???? We've been to St. Louis and Gulf Shores in the past and had a great time but I wanted to try something different this year. I still have a little while to make decision. Maybe I'll get it together by the time the summer officially rolls around. :)
