Thank you. I was started to wonder about Viator because as I did more research, I discovered that they were doing this on behalf of some other company, ...the name eludes me now but I thought it started with a D. As far as doing something on our own.....my whole exploration attitude started expiring about a year ago. I am now becoming a little afraid of wandering around not with a tour group. My husband and I are up there in age.... I wish I had done alot of this traveling a while back. My comfort zone right now basically rests with just Disney World, for what it's worth, lol.
