Has anyone done the Cartagena hop-on hop-off bus tour?

Has anyone had experience with this hop-on hop-off bus tour in Cartagena?

Also, is there a HOHO bus stop at the port?

From memory, on our NcL cruise, we had to take the ships shuttle into town and caught the Ho Ho bus from there. But that was a Ho Ho bus tour offered by the ship, using the Local Sightseeing Ho Ho bus, so open to others once in the town.

Same bus as you show in your link.

I DO NOT recommend the on & off trolley. First it is a $20 taxi ride there & when we got there NOONE spoke English. Talked to @ 10 different people, even a police officer & no spoke English. Decided jut to go back to the port area & none of the taxi drivers spoke English. Kept showing them out ship card & saying cruise ship. Finally the fourth taxi, the guy said cruise ship so another $20 taxi.

Sounds like fun, did you find any reviews?

Our ride on an AC tour van was very nice but there is SO much traffic. I would have been very uncomfortable on a regular hop on/hop off experience. Very hot there!
