Thanks I'll have to stop by the library this week
Another suggestion regarding guidebooks is to check your local library (or libraries). The editions they have may be dated but it is worth taking a look at any you can get your hands on to see which you feel is worth buying in a newer edition. GusGus77 loved The Unofficial Guide but was bored by Birnbaum's while I recommend Birnbaum's and find The Unofficial Guide to be more like a plan of attack for the commando visitor. Everyone has their own opinion and every guide has their fans so you can buy all of them or try to figure out ahead of time which one is more your speed.
