SessionStack

Plan your AWS re:Invent 2026 week without the spreadsheet chaos. 2200+ sessions across six venues on the Strip. Ask in one sentence and the AI turns it into filters you can see. Leave an afternoon open and it suggests what is worth your time and actually reachable. And it will never book you two talks twenty minutes apart at opposite ends of the Strip.

ContactBook's advantage is device support (3 vs 1) and ratings volume (3 vs 1). On price, ads and iOS requirement there is nothing between them.
