Bellasmom,
Welcome to the Arnold. We live 20 miles from Columbus so the Arnold was on the schedule every year for the 12 years dd was in usag jo. Haven't been for 2 years since she is now an ncaa gymnast. The Arnold is a good meet, well run, good venue, nice awards, and Arnold does give a welcoming speech at some sessions. My knock on the Arnold is that gymnastics is only a small part of the entire event and you have higher than normal costs for admission, parking, concessions, etc. I recall one year we had an afternoon session and we had to park blocks away with a long cold windy walk to the center as all the closer garages were full. The Columbus Convention Center is a huge multi-level building. It's easy to get lost in it and there is always a gigantic crowd for all of the on-going events and exhibits. Lastly, Columbus is March is not exactly a vacation wonderland but for all that it is a fun meet. I hope you enjoy your stay and good luck to Bella.
