Plan ahead as the playoffs advance by scouting out your possible ticket possibilities in various cities and on the Internet. Sources could range from websites to area ticket brokers to contacts you might have.
Likewise, look into the hotel situation in advance and book as soon as possible. Try to find a place near the ballpark so you won't have to drive-or fight off a hoard of people for a post-game cab.
Find out the best sports bar around for some post-game potions. The big flashy taverns can be fun, but you'll find even more hardcore sports nuts at the old-time local establishments.
Consider going with a group-either your baseball fan buddies or on an arranged vacation. What could be more fun than heading to the World Series with a bunch of other crazed sports fans?
To make things interesting, print up some trivia questions about the World Series and/or the teams involved to quiz your travel companion(s). A long car drive could also be enlivened by listening to some CDs of classic World Series moments, which could also build up some additional excitement as the game approaches.
Take along some foods and beverages inspired by the cities that are playing. A road trip to see Boston vs. San Diego could include beans and fish tacos, for example.
Root yourself hoarse, live it up and bring back a cool souvenir from the stadium. You only live once!
