1. Decide where you want to go, new part of the country, places you've always wanted to go, maybe knock 2 birds out with 1 stone approach.
2. Check the MLB schedule and when the home city will be in town, this is not always as easy as you think!
3. Map out home cities with teams' schedules and make sure they synnchronize so you'll see the teams when you are in those cities...in other words don't go to NYC if Yankees and Mets are not both at home within 2 weeks of each other...pick another place to go or another time to go if possible.
4. Plan where you will stay (Hotel for us, will you walk to stadium, drive, cab, public transit, what's the best area for families/kids...near ballpark or no?)
5. Leave enough travel time for the unexpected (traffic, detours, weather, etc.)
6. How long will you stay in each city? (We stayed longer in cities such as Chicago, Wash D.C., San Diego, etc. that have lots to do...we stayed shorter in Milwaukee, Detroit, Cincinnati, etc.)
7. Buy your tickets on-line thru the MLB team site if possible, saves you money rather than going on StubHub, Vertex tickets, or other sites that will jack up prices. Don't risk buying at the stadium, you may not sit with your family.
8. Decide on other things you want to do in the home city...any other site-seeing, things you must do while you are there?
9. Take lots of photos! These stadiums are so very different, enjoy the unique qualities of each.
10. Buy a souvenir from each stadium, either a different trinket from each place or something of the same from each place (we buy a baseball from each stadium)
Have fun! This is America's Past-time!
