First of all, when you're in your room, put out the DND sign - period. You will avoid any intrusion. Secondly, I find it offensive for you to point out that a male sitting in a seat should simply give it up just because you (a woman, and holding a child), think you should have it, just because you're holding a child. Male or female has nothing to do with it. Yes, it;s the polite thing to do, but for everyone. All those people have been walking just as much as you. Also, since you stayed at a WDW resort, you could have had your purchases sent to your resort, and not had to carry tons of bags. And, depending on where you're staying, your bus stop may very well be the last stop. Do a little research when you get there, find out where the bus stops are, find one that may not be the last one, but may still get you back in a resonable amount of time. The buses may leave empty because they're going to a DIFFERENT area than where you need to go...
Yes its WDW, but you also have to realize that the CM's are people too, not Audio Animatronics. They have to deal with thousands of guest's, some nice, some not so nice-my meaning-it wears on you. You need to understand that, as well.
I truly hope you go back and have a better experience, but do some research on the transportation system, You'll be glad you did. We always drive or rent a car for some of the reasons you speak of.
I'm not trying to bash you, but WDW is it's own major city-if you will. You and your family will benefit from doing as much research as you can for your trip. The majority of us on these boards have been to WDW multiple times, and can't say enough about knowing where you're going, how to get around, and what to do. Sounds obvious, but none-the-less is very true.
just my 2 cents.
