We spent 3 hrs in the Museum, it was not crowded, we took our time and really see everything in it ! .. @ hours should be enough if not crowed ! it seem like it was the last stop on bus tours and got packed as we were leaving ! 2 ship in port last visit.
If I remember right 7 yrs ago we walked to citadel, it was a up hill walk !
we will also be there 10/6/22 but use mobility scooter now ( started June 2022)
enjoy u trip the walk front is real nice with lots of place to snack or eat/drink
