My initial plan on arriving in Istanbul was to catch an early morning ferry out of the city and then making my way down by train to Izmir. However, now that I think of it, this plan sounds like an awful waste of one whole day travelling when I could save money travelling by overnight buses instead.
So my new plan is this: stay for a night in Istanbul, and then catch a(n) (overnight) bus to Bodrum the next day (on Sunday). I have seen this list on Turkey Travel Planner for buses to other cities from Istanbul and it appears that there are multiple bus terminals from which buses depart. Which one do I need to go to catch a bus to Bodrum?
Also, any idea about what the schedule is like, i.e., how frequently buses run between Istanbul and Bodrum (especially on Sunday, which is when I want to leave Istanbul)? The only site I've found lists timings only for one company (Aydin Turizm) and seems to suggest that there's one bus that leaves at 9.30pm.
