We did the trip to both places last year, you just need to go along the promenade and speak to the tour operator,s there they a do the 2 day trip, i think it cost us about £40.00pp.
Ephisus was beautifull and very interesting, Pammukalle was most impressive, you can walk along parts of it with NO shoes on as it ruins it(although some people take no notice of this), it is a long trip on the coach for them both, but certainly worth it..
Have a great time,
