As with everything to do w/travel right now I found this somewhat confusing. Does it mean I will be able to fly to… https://t.co/3vWRb9UVPz
NAZİLLİ
Population: 144,000
Ottomanesque fountain made from a 19-ton block of Marmara marbleMarket day: Every day except Friday in central covered market area
There's not much reason for you to stop in Nazilli unless you want to use it as an alternative base for visiting Aphrodisias via Karacasu or for getting to the ruins at Nysa.
If you do stop you'll find a small private ethnography museum facing the station that may or may not open. Also facing the station is the Uzun Çarşı, a pedestrianised shopping street cutting through a bazaar area.

Sleeping
There are a few cheap places to stay near the station but you probably won't pay much more to stay in the more comfortable Hotel Metya, opposite the bus station and perfect for early departures.
Transport info
There are minibuses to Nazilli from Aydın and Denizli but given the problems with Aydın otogar you might be better off taking the timetabled train from the town centre.
