We are headed out for four nights in a few weeks and we generally like to see a show every night. I've booked a couple shows already with MyVegas, but we were thinking of waiting to get out there and using Tix4Tonight. I've already booked Love and Rock of Ages. My questions are: Are there generally a good selection of shows each day? Are the service charges crazy? This is our 11th trip to Vegas and this is a big step for me to buy tickets on a whim when we get there. I have the tendency to go into "Clark Griswold" mode when we travel!
