Accomodation Booking question


I’m looking for some advice. My topdeck tour ends in Greece at the end of May, and I plan to stay there afterward for about a week. I’m not quite sure which islands I will visit yet, but I’ll probably stick around in Athens for a couple of days. Do you think I need to book my hotels ahead of time? Or will I be fine just figuring it out while I’m there?

Any advice will help.
