Things to remember:
Adequate power is the most important thing about picking a venue. Don’t trust them if they say it’s fine. Try to test it somehow with an engineer or electrician.
If there isn’t a hotel attached, do your best to have one within a short walk.
Use Ticket services like Eventbrite instead of using a bank to process your transactions will reduce a lot of headaches and fees as you pay some of the fees and some are passed to the attendees. Also those services fight chargebacks for you (you will have them).
Plan as far ahead as you can, and find as much help as possible. Haha.
Good luck!!
