Mrs
Thanks for any comments that might be helpful to other clients, but in your case you are not being honest at all.
you paid for a half-day tour of 5 hours, and you wanted to do another 10 hours tour in which you paid the deffirance, moreover I remind you that the oceanographic museum is not included in the tour, but you can visit it in your free time on your 2nd tour.
Madame be honest, because you have the wrong time you were with a professional guide and always rated 5 stars ...
