Stayed at the Tui Blue Grand Azure, which I can definitely recommend, big pool, right on the beach, 5 star. We managed to snag one of those beach beds on one of the days which was all kinds of awesome, whole day lying on a 4 poster bed on the beach getting smashed.
Oludeniz is nice but hotels are more expensive, but if your going in the summer try up the hill in Hisoronu which is only a dolmus (bus) 5 min trip away It’s really hot during the day but at night it dropped to about 20 If your at sea level it stays hot all the time Just something to consider
