Generally speaking, this tour is fine, it takes passengers to some great spots for photos (particularly the bridge) and the bar where we disembarked for a drink and some music was fun. As someone who really doesn't get into country music, I appreciated the drive down music row in particular because the guide was able to explain to us the significance of many of the buildings (who recorded at the studios, famous agents that operate out of the offices there, etc). Unfortunately for some passengers, your ability to take pictures of half of the sights is limited depending on traffic and what side of the bus you're seated on -- I recommend going for a seat on the left (behind the driver). Anyway, overall it was mostly worth the money.
But a note about my experience-- I'm a youngish woman who took this trolley by myself. The guide, Bert (I think) was obviously very knowledgeable, and a bit uhm, "extra" (tried to lead the passengers in song throughout the tour, etc), which was fine. Most of the other passengers were middle aged couples who had been drinking, so it felt a little like a party bus at times, which again, is ok.
However, the bus driver made me increasingly uncomfortable throughout the tour by watching me in his rearview and insisting I take his hand when I stepped on and off the bus (which at first I thought was nice but after awhile it turned awkward). This progressed to him pressing my lower back (way low) as I walked to my seat (wildly unnecessary) and then, when I got off the bus at the conclusion of the tour, he again took my hand and as I said "thanks" and started to walk away, he WOULD NOT RELEASE MY HAND. I had to turn back to listen to him "apologize" for having to seat me with a trio of younger guys (who were all gentlemanly, sweet and attractive dudes from Manchester, so hardly an inconvenience for me), all the while with him still holding on to my hand. I had to yank free. I'm sure this dude thought he was being chivalrous or that we had a bond or something, but unfortunately my discomfort with his totally uncalled for touchiness is what lingers from this tour. Shame, because the security of taking a tour bus was very appealing for a woman traveling alone who wanted to see the city at night.
