More than One Regional?

[smurfgirl]

Thanks for all of the responses, you're definitely offering me a lot of insight. More responses to my first questions are certainly welcomed and encouraged, but I also have one more question to add:

For a team who wants to attend two events, is it better to do two regionals, or one regional and the Championship?

Edit: I also thought of something else I'd like feedback on- some posts have mentioned a "warm-up" regional, with lower pressure. Our team recently started using a full-scale practice field, and we simulate competitions with loud music, spirit teams, defensive robots, running pep rallies, etc. We also go to a scrimmage before ship date. I know this is not the same as a regional, but it does get in a lot of individual driver practice for technique, as well as six-robot driver practice. Does this change the idea of a first regional as a "warm-up" at all?
