Now that you're almost 50, glad to hear you're making some good decisions- I don't know if we ever outgrow the need for others' wise input though. Kudos to your friend for offering wisdom!!!

I think your parents will be fine on the bus- who knows, they may even have more fun with the others?
Of all the FW Pavs., the Land is my fave. Who wouldn't enjoy seeing the world's largest tomato plant?? I mean it's like Madam Tussauds gone real and not macabre.
Yes. know the stroller drill!! Thank God we're done with THAT!!!
Never really explored The Seas more than seeing the lame clamobile ride and Crush. Need to remedy that. But, I"m like you- a little reluctant to start the exploration process- since I have to read all the stupid placards that will fill valuable brain space with pretty useless info. - what little I have left... And I have to see ALL the exhibits, and take too many pix, that won't turn out... in short spend far too much time in the end.
