Dolmus times

Hi we are staying in marmaris this year,weve been to icmeler during the day but would like to have a few nights out there,after looking at the photos of the pubs/bars/entertainment on this site.As theres quite a few of us to save getting 2 or 3 taxis any idea how late the last dolmus leaves from icmeler back to marmaris.Also as weve only stayed in marmaris for entertainment any tips for the best bars for us to go to,we like to be in a great party atmosphere:karaoke etc.Thanks
