Locals tend to avoid the strip if possible. When I was local, I preferred incalls and usually had to book a room (cheap midweek room off strip) as most reputable providers were outcall only. While I don't think it'll be crazy busy when you're visiting (I thought I read re:Invent last year only had around 1700 attendees but the convention calendar claims 65000 vs a room inventory of close to 150,000 give or take in the county). NFR starts on the 5th but that shouldn't affect you during your stay (the airport might be busy).

If you guesitmate 10% of those convention people are hobbyists, you're probably competing against 6500 guys looking to get laid (way more if you count tourists in town). Figure out who you want to see and secure that appointment in advanced. It'll probably start late and on occasional will be cancelled, based on my experience. Most of my Vegas sessions were good times.
