Balancing market time, coast time and free time without overloading the day.
Fethiye and Ölüdeniz can fit into one day, but trying to add every nearby attraction usually makes the schedule too heavy.
A simple flow is market and town time first, then Ölüdeniz in the afternoon. Alternatively, skip the market and give the coast more time for a slower day.
Summer traffic and beach crowds can affect meeting times, so the return plan should stay realistic.
