Hi bishbash,
I did a thru-hike this year from April 1st through October 9th. I think 60 paid stays is a bit excessive. I spent 30 in hostels and 15 in hotels (and I thought that was way too many). Plan to split hotel rooms with other hikers. You will meet and end up hiking with lots of other hikers. Also, the hotel rooms are cheaper in the south than in the north. Hostels run from $10-$35, but typically $20 is about right, but again more expensive the further north you go. Not only is it acceptable, but it's very common. I never saw anyone with vodka though (most drank whiskey or rum). I'd keep an eye on the weather. It might be better to shoot for a mid-March start date. This year the weather was wacky and very cold with a late spring. Many people who started early ended up sitting out a lot of the weather for a week or two. If you're concerned about the heat, what some people did was to get up extra early and start hiking before dawn, find a good cool, shady spot around 11:00 or 12:00 and take a break for a few hours out of the high point of the heat, then hike on after the sun begins its decline in the sky.
