In turkey, there are a lot of touristic areas all depending on what you wanna travel for
anything should be pretty cheap as well since our currency strength is shitting itself as of right now, your $1 would be worth $4 here basically
if you want to have a chill holiday near some real proper shores where you can swim for hours on end, take part in social events etc. i'd reccomend going to places like Antalya, Çeşme or Bodrum (which i will be going to this summer)
as you might know, Turkey has shores to the Mediterranean sea, part of which is called the Aegean sea here ("Ege denizi" in turkish)
(picture of the place ill be going to, its named Sea Garden)
If you wish to go sightseeing we have a bunch of those kinda places as well Türkiye'den 20 Doğal Güzellik - Haberself look at the pictures in that link for reference
if you are interested in sightseeing then i recommend travelling to Istanbul first, then buying tickets for a tour bus that takes you all around the country and lets you take a good look at all the interesting places for short periods of time, with the help of a tour guide
summer, unless you wanna do snow related sports, which i dont think youd wanna come to turkey specifically for that
No specific places but most foreigners find traditional turkish food to be unique and nice
Nah, all alcoholic beverages are imported and pretty expensive here, but you wouldnt have a problem drinking as there is no legal drinking age although if you look under 18 you might not be able to buy any (im 16 and they sell me alcohol cause i look like a 18-20 yo lul)
