I am interested in going to an Angles game between April 19-26 when they have a home stand vs Seattle/Yankees/ Bosox.
I'm wondering about availability and the best way to get 4 seats at the best price?
I don't want to by in advance, I'm just going to show-up on the day I deceide to go, so I am wondering about the availability at the box office and/or through scalpers. Is scalping allowed(or at least tolerated)or must you buy at the box office?
Will there be better availability for any one series?
Thanks!

The Sox will be the easiest tickets to get, the Yankees, the most difficult. Still, you shouldn't have a problem getting tickets from the box office (perhaps problematic getting good seats for the Yankees without paying a premium). Here in L.A./Anaheim, we have a big group of transplanted New Yorkers, which is the reason the Angels/Yanks and Dodgers/Mets games are so well attended. Obviously best seats for the weekday games, followed by weeknight games, and the hardest being the weekend games. It's easier to get tickets for the Angels than the Dodgers, but both are readily available. And, yes, there are scalpers outside the b.o. (by the parking), but getting 4 seats next to each other from them will be a problem. Usually 2 or 1, not 4. Wait until the game starts, and the price goes seriously down.

Just go to the stadium box office the day you arrive. Some or all of the games will have good seats available. So you can work with the agent in the boxoffice to get the best available seats for whichever game fits best into your plans. Absolutely no reason to go to an agency or scalper.

you can always get to the stadium early and walk around looking for someone who has extras - but maybe four together would be difficult. That's the only way I ever buy tickets at any stadium, and I've never paid more than face value, although i've often paid less.
I imagine the Angels have good attendance this season, but in seasons past, the ushers were unbelieveable and would sit people with crappy tickets along the baseline to fill those seats up.

I don't know about Angels' tickets but I got a ticket to see the LA Dodgers play the Padres last week for April 15th. I bought it over the internet and they mailed the ticket right to me. I suspect, you can get Angels tickets over the internet as well.
