A few suggestions and possibly missing items.
Essentials that seem to be missing, sorry if I missed something.
1. Arrangement of local transportation.(Rented car/taxi).
3. Converting Registrations to badges and getting them
printed(assuming we are giving them to a printing business).
4. What about breakfast? It would be nice to have some other
organization to sponsor this.
Will be nice to have someone put together things like(for the booklet):
1. Local restaurants.
2. Places of interest nearby.
3. A map of the venue and the city (assuming we don't want to use
google maps), with landmarks such as ATMs, Pharmacies etc.
4. Emergency numbers.
and so on.
In addition to wireless, we should check the number of power outlets at venue.
Also, do we require backup power in the venue?
