What is your tour ?, some tours start on tenders direct from the ship. My advice is to wait until you are on board before making any plans. We have been to Mykonos three times with Celebrity on Solstice, Reflection and Edge. Each time advertised as tendered but on two of those visits Solstice and Edge actually docked at the main ferry port where most bus tours start from and is some way out of town needing a bus or ferry to get to the town. Looking at Mykonos port schedule for the 13th the only other ship on that day appears to be a sister ship Constellation and I would guess Beyond will dock despite having superb tender facilities.

This is exactly what I did and it was accepted immediately. We had to show the printed (or on the NHS app) pass at the port anyway.

When we went to Valencia on Equinox the port authority only provided a shuttle to the port gates as it can be a very long way from where the ship docks. After that it's still a very long way to the centre of Valencia. The question is do Celebrity provide a shuttle, they did provide one and it was not free. It took you to Placa de la Reina. We didn't use the Celebrity shuttle as we wanted to visit both the centre of town and the modern Museum of Sciences which is a way out of town. We used the port shuttle to the port gates and then used three buses, one to the centre of town, one to the Museum of Sciences and one back to the port, each approx two euros, so twelve euros for the two of us which was a lot less than the cost of the Celebrity shuttle for one person although thats not why we did it. The buses are frequent clean and quick and a map can be picked up online or at the port entrance information office where the staff told us which three buses to catch, the first into town is right opposite the port entrance and also goes to Placa de la Reina.

What route ? Which UK airport ? If you booked with a Celebrity agent in the UK they'll book (at least give you a price for) whatever airline you choose within reason from and to the destinations you choose. for example I always choose Emirates as they fly from Birmingham.
