Yeah, it’s pretty chancy. I mean, crowd levels the second week of November are lower than, say, late December, so your chances of doing what you’re planning are higher than they would be at Christmastime or during the summer. But you’d still be taking a gamble.
The convenience or inconvenience of having your own
ECV for the duration of the trip can depend on the mode of transportation you’re planning on using and where you’re staying. If you’re using Disney transportation (buses, boats, monorail, etc.) and staying at a Disney resort, then taking the ECV with you when you hop shouldn’t be an issue. And there can be a lot of long hauls to walk back at the Disney resorts, too.
However, if you’re driving everywhere, have a smaller-size vehicle, and are staying offsite at a hotel where you can park close to your room, I can see where it might be more bother than it’s worth.
