Hi! We'll be arriving in early May at Mykonos via cruise ship. Its says on our itinerary that our ship will be tendered and we will be there from 7am-6pm. Originally, we planned on booking an excursion through the ship but the excursion that we wanted is already fully booked. Can anyone recommend a good, reputable travel agency for a day tour in Mykonos? We are a group of 18 people so it will be hard for us to do an on our own tour.Thanks!
