All really good advice. Especially about deals in the exhibit hall. I find that it's better for my wallet to get what I can't do without the first day and pick up the stuff that didn't make the cut the last day. If it's not there, it wasn't meant to be.
Whatever you decided I highly advise that you have the next day off of work to relax.
Women and cats will do as they please. Men and dogs had better get used to it.
