I dont think your young boy will have any probs in
Marmaris ( re drinks or bars). Its you that may have a problem ( sorry sir you are to old to drink in this funky, trendy bar.)

Only kidding .!.
We stayed in the Siteler area of Marmaris last OCT and It cost us 20 Lira for a taxi into Icmeler. It also cost us 10 Lira from the Siteler ( spelling) area to the main area of Marmaris ( ie bar street area).
So as to give you a rough idea on taxi price from Marmaris centrum to Icmeler.. I would think 25-30 Lira before midnight.
Hope this helps.
