Do I want to be in Seville for Feria de Abril?
 

Looks like it might be fun. I don't mind crowds and would not be there on the weekend, which from what I've read might be a million people! Has anyone been in Seville for this festival? What was it like?

It's a great festival, but unless you know someone, or go with a group, it can be difficult to experience it. If you think you might enjoy it, then by all means go. There will be more than a thousand “casetas”, tents, where the groups gather. Who knows, you might get invited to join one of the groups. It's happened more than once. The fiesta takes place at the fairgrounds, so the rest of Sevilla is pretty normal.

Thanks, Robert, I appreciate the input. As it turns out, I tweaked my itinerary and I won't be in Seville during the festival.
