The guides, as always, had some good information and gave great tours.
However the big bus company seriously needs to expand their amount of busses and have them come more frequently.
We were always waiting for quite a long time and saw multiple busses of other companies pass...
For 100$ for 2 people, it is very expensive... Also they sold the tickets with 'wifi' on the bus, but once you were seated the guides said there was no wifi. Very disappointing...
It's better to take an uber to wherever you want to go, or just take another company like starline (no experience with them, but I suppose it can't be much worse)
