Calis is not like Blackpool, you need Bodrum or Marmaris for that. If you have not been before, give it a try first.
In Calis/Fethiye you can be as Traditional as you want to be. Might be nice to stay at Tlos but it depends what you want from a holiday, if you want quiet peaceful 40 minutes ride from shops, bars, clubs and restaurants you must book it.
