Not quite. I meant that if it was TOO easy to walk out the door to the attractions then there might be (1) increased resistance or difficulty for some people to attend TAM, especially if it is on a corporate or scholarship dime; and (2) lower actual attendance at the convention presentations.Isn't part of the reason to have it in Vegas is because of its attractions? Why have a convention in a city like Vegas then set up "obstructions" to wandering around places like the Strip? May as well just have it in another city then.
We once had a computer users' convention at a hotel adjacent to a theme amusement park and golf course. We found the presentations more poorly attended than expected because people were sloping off for 9 holes, or for a few rides on the roller-coasters, etc. There were also complaints later from a few corporates about such "unnecessary temptations"...
Put simply, make it such that if people want to "do Vegas to the max", they will find it better to organise it for before or after the convention, or out-of-hours.
