In the US, a typical weekend tournament is run as a five round Swiss--three games on Saturday and two on Sunday. Longer events, such as many held this weekend, may have fewer games per day, or more games. They also may have longer time controls.
In my city these are nearly always G/120 (two hours per player per game). Play starts at 10 am and ends at 11pm on Saturday, but Sunday goes only 9-5. I usually get up while my opponent is thinking to check out the other games, and because I drink a lot of water (and some of the bad coffee they supply), to make a trip to the loo.
We are expected to bring our own sets and clocks, but not everyone does. According to the USCF rules, the player of the black pieces supplies the set and clock, but we have a preference for clocks with a time delay (G/115 + 5 second delay), and I have an analog clock. I usually bring a couple chess sets--a nice one that I prefer to use, and a cheaper set if I'm playing a certain player that is subject to temper tantrums (it took a week to get all the soda pop stains off my pieces after I scored a draw in a dead lost position when his flag fell a few years ago).
