Where can I pay with an Octopus card in Hong Kong?

I want to take a dolmuş from Ölüdeniz to the Lycian tombs, but I can't figure out where is the best place to get off? Is this going to the center of Fethiye?

Can you arrive at Caselu without a prior reservation, just at opening time, and buy tickets for everything you want? Or do you need to book in advance for feeding the giraffes and petting the cats? And how far in advance do you need to sign up with Bruno for whales?

Please tell me how to get from Mekki to the market Kakiy.

Could you tell me if there are places for swimming with a SUP at the reservoir? My friends mentioned in 2023 that there is a spot with shallow islands that you can swim to.

Could you please tell me, in Marmaris, is it possible to pay with 2006 dollar bills at Migros, Vakkolo? I've heard that old bucks are not accepted... I don't want to take euros.
