It is opposite the bus and taxi park at the entrance to Side.

Wij hadden geboekt via de reisleiding in het hotel (neckermann) en betaalde 49€ per persoon voor een hele dag rondleiding waar het bezoek aan het amfitheater een onderdeel van was.

Hi, not sure about Hotels in the area but if you use Tripadvisor and add filters it’s very good at finding just what you need. The whole area around the amphitheater has restaurants within a five min walk in any direction, the ones on the sea front are very nice if you like to sit and watch the sunset. Once again I checked Tripadvisor and if the reviews were good and they were reasonably busy it’s always a good sign. Hope this helps

For adult was 20 Turkish lira and child I don't know :)

Neen dat zijn alleen maar oude gebouwen

From 8 o clock

Das Hotel kenne ich nicht. Vom Hafen am Tempel vorbei. ca. 10 Minuten zu Fuß

Там развалины под открытым небом. Без билетов и времени работы.

They would always be open, as they are all clearly seen by the side of the road, just walking along the footpaths will bring you to all of the ruins, there are no entry points. Its a lovely walk on the beach path, then when you reach as far as you can - you take the path that brings you to all of the ruins and then the small harbour and little village.
