Does anybody have any experience, tips or tales about First Night Annapolis? (Annapolis, Maryland USA)

(First Night Annapolis (FNA) is an annual New Year's Eve celebration of the Arts, showcasing hundreds of performances of music, dance, theater, comedy, and more for audiences of all ages and tastes.)

In particular:

• Dress? (I'm looking for an excuse to go in costume...)
• How's Parking?
• How's the (ahem) sanitary facility situation? (Porta Potties...)
• Is it ungoshly crowded, or just cozy?
• Is this an alcohol free event?
• Is it far from venue to venue?
• How bad is the exit traffic?
• Any other pertinent info or ideas

These questions are only partially answered by their website, so personal anecdotes are appreciated
