I have played both on paradise and many lv tourneys. Paradise tourneys last no more than an hour.You will get much more play in vegas, they run 4 to 6 hours for the small buy-in tourneys. Best tourneys IMO, are at the Mirage and Orleans, you will get more players and the biggest prize pools in these tournaments. Orleans tourneys $20-60 buy-ins with multi-rebuys or at least 1 rebuy the first hour, levels increase every 20 minutes. Mirage $60 to 120 buyin, multi rb 1st hr, 30 min levels. I played mir tues. nite and next to me was a wsop gold bracelet winner. Usually very tough locals at both of these locations, but with a little luck and patience you can make it to the final table. good luck to you.
