What's your budget? That may largely determine how you travel since it's late to purchase airline tickets now.
Can people get out of school/work to accomodate a bus trip (it's a two day trip for me so we're leaving here on Tuesday to drive down so I can volunteer down there - so it means two extra vacation days from work vs. flying down but I can't afford to fly).
Will you have to have a layover? It was a 12 hour trip from Hartford to Atlanta via Chicago if you consider layover time, plus time to travel to the airport and arrive early so the whole group can check in together, plus the transportation from the Atlanta airport to the hotel... and if you get stuck due to bad weather, it could take even longer.
Will you have to stay overnight in a hotel on the way down/back if traveling by bus? Could add more expense to the trip.
Will you be attending the wrap party on Sat night? It's got it's flaws but I still enjoy it.
