YES! Even if you just want a goodie bag, you have to register. They will not give one to you unless you are registered. The registration will also get you a name tag. Don't forget to sign up for the HRI reception (its free but they would like to know how many are attending!) or any of the other functions. Some are free, some are not. The boxed lunches are a great convenience as it can get pretty pricey eating at the restaurant.When it says registration is that for those of us who have to pick up our goody bags?
