Aside from the above piece pieces of advice I'll echo that you should check the previous histories of which events fill the fastest. Last year we knew the Northeastern District event would be a high demand event due to accessibility to a large number of teams and the date which is why we registered for it as a Week 5 event before UNH Week 2.

Also come up with a backup plan come time for second event registration in case the second regional you register for fills up. If you've already discussed alternate plans and other regionals you might consider it will increase your chances of being able to register for a second event instead of waiting until your team meets again to discuss alternate plans. Every hour you wait after event registration opens the less options you have near you. Ever since 3467 started attending double events in 2012 we've always had a backup event ready in case we weren't fast enough. Boston 2012, Connecticut 2013, Byrant/Lewiston 2014, etc were our backups events in case our top choice filled up but thankfully our Coach has quick hands!

Hope for the best; plan for the worst!
