Hi Happydodo
The obvious here is to contact
ICR about any trips, but I have to say it is getting late in the season for big excursions, these places you mention arnt 5 mins away
Turkey is a big country and a lot of places you see in magazenes etc are hours away and require a lot of organization. Ephesus itself is a good 4hrs drive and the tours usualy include Pamukkale and involves an overnight stop so that you can get the full experiance of these wonderfull places, Dalyan is only an hour or so.
No doubt ICR will come back on this if you ask them.
Regards
Peli
