We want to take the high speed train from Istanbul to Ankara, then the bus to Goreme. Some questions:
Should we get our train tickets in advance for an August trip?
I've read that there are plenty of buses headed from Ankara to Goreme, but online I've only found one at 3:30pm. Will we have more choices of tickets if we wait until we are in Ankara? Is there a place to leave luggage at the station? Is the area around Ankara station one that would be interesting to explore for a few hours?
I've read that some buses will leave people at Nevshihir rather than Goreme. How hard is it to find a bus or taxi to Goreme if we got in at 7 or 8pm?
