greenshoes,

According to the Marmaris map ...

Soykan is at no. 112 (you have a slightly different spelling)
Seler is at no. 185
Hasinci is at no. 0

They are all pretty well spread out. Hasinci I believe is down the Ataturk Statue end. Seler is somewhere up behind Migros and Soykan is best described as in the middle of the two. I'm getting these locations from the Map and don't know the Hotels themselves. I'll put a link to the map on for you.

Hasinci is next door to the Seler and a long way from Ataturk Statue. 5 minute walk from Migros
