I will agree. Do not go on the weekend. If you do go on a weekend, go early in the morning and leave by 2:00 or so. The last time we went, by the afternoon you could hardly get around. Lots of the locals come on the weekends. Mainly lots of young people drinking around the world.
During the week is great. Also to keep track of how much you spend, get one of the cards they sell. You can put whatever amount on it you want and is a great way to keep up with how much you have spent at the F&W.
