We have a yearly conference that my company attends and it has always been at the Sands Expo since I've been working at this company. The Sands is in a good location which is easy to get to and there are plenty of food options while at the expo as the Venetian is connected. The food is a bit pricey both in the hotel and the Sands but seem to go with Las Vegas in general. The sands is a large space and has many rooms that are typically used for different parts of the tradeshow. The sands staff seem to be pretty helpful and the the tradeshow is pretty heavily attended.
