We'll be flying out on 2nd August for our first Icmeler holiday (woooo!) and just stumbled upon the forum so there may be a few questions over the next few days

We picked icmeler mainly because recommendations from friends indicated that it would be a nice place to just chill out and have a lazy holiday.
We've tended to hire a car for our hols for the last 10 years or so, but this year I haven't got round to it. In other places, we've used the car for sightseeing trips (say for less than a 50 mile radius) and days at quieter beaches that are more than a walk away so I'm starting to wonder whether i should reconsider and hire something anyway.
1/ If we were to hire, would people advise booking from home or waiting until in the resort?
2/ Are there any beaches or sights that more than a walk away that would make hiring worthwhile?
TIA,
Mike
