HI!!
I can't answer the questions about November weather, lines etc (except I think that would be a great time to go) but I can answer the other questions since we just got back from our stay in a cabin!
We stayed in 2100 loop which I think was perfect. The bus stop is right across the street, and you can walk to the Meadows Trading Post and Pool. The Trading Post is where you can buy milk, juice etc. It is a little pricey but ok for a few things. We ordered from Garden Grocer and had most of our stuff delivered! I also sent a box from home with snacks, peanut butter, smores supplies, etc. It worked out great. We rented a golf cart for one day which was fun but certainly not necessary! We were in the parks 4 out of 6 days so the cart would have been just sitting there the rest of the time - and at about $50/day we just couldn't afford that. We got used to riding the bus and never had to wait long!
We can't wait to book our next stay at FW! It really is a great place to stay!
