Hi Susan,
Thanks for visiting the Moms Panel!
You are right on target for dressing to accommodate the usual November weather, which is some of the best we have to offer in Florida: Highs in the upper 70s, lows in the upper 50s, with little rain and lower humidity. Of course, you never can be absolutely sure what Mother Nature has in store, but you should be comfortable in shorts all day and need just a light jacket or long sleeves at night.
Regarding
La Nouba by Cirque du Soleil, you can get same day tickets if seats are available. Tickets can be purchased online, by phone or at the La Nouba venue in Downtown Disney. There normally are two shows nightly Tuesdays through Saurdays. They sometimes sell out, and you have a better selection of seats the earlier you book.
Please let us know if we can help with other questions as you plan your November visit. Enjoy!
Wilma
