Yes!

Καλημέρα. Το ενιαίο εισιτήριο ισχύει για 3 μέρες. Την τέταρτη μέρα, όταν γίνει ο έλεγχος, θα σας ενημερώσουν ότι δεν ισχύει το ενιαίο. Από κάθε μουσείο που περνάτε σας βάζουν μια σφραγίδα και σας ενημερώνουν σχετικά.

If you are asking how long it takes to go around the museum and Gardens then I can tell you it took me about two and a half hours to completely see everything

We bought pensioners tickets which were about 5 euros that enabled us to visit all museums in the old town which were within walking distance of each other.I was blown away by the gardens of the archaeological museum which we left until last , This as a good plan as we spent a long time roaming through the gardens and the various buildings. A real bargain - Grand Masters Palace, Archaeological museum. The jewish museum and synagogue was very cheap and well worth a visit, although it moved me to tears

Yes only a few minutes walk away but in the heat of the day take protection. Hope you enjoy them both.

Comme partout en Europe, le musée archéologique est fermé les lundis. De plus, les Grecs sont très pieux et ne travaillent pas pour les grandes fêtes comme pour Pâques et Noël. Il est ouvert du mardi au dimanche du 8,30 à 14,30. Prix d'entrée est de 6 euros.

Tue-Sun: 08:00-16:00

To be honest it's a little archway as you enter. We thought it was shut when we popped our heads in. It's not well sign posted though. We entered from the south entrance, it should be then on your right.

If you will see proprelly, 2 to 3 hours.
