The tour was great, the staff on the trolley were knowledgeable and friendly. The only improvement I would suggest is to have more directions on the outside of the gift shop that explain what the check in process is and what to do, because the staff inside that are supposed to check you in aren’t particularly clear with what you need to do. The experience of the tour was very interesting, once we figured it out.
If you are heavy set like me, be aware that the seats are a bit small and are ideally for 2 relatively thin people to share unless you are in a group of 5 or more and manage to get a seat in the back of the trolley.
I would do it again for sure!
