There are a few places to stay on the island. I'll put a map below of where the venue is on the island. The main place to stay is Kamari as it's the main tourist spot with lush strip of shops, bars & restaurants.
If you want the classic Santorini dome roof cliff views then that's a bit more spenny up in Oia.
I will list some hotels below of different areas of the Island however I am sure you will all establish your groups & book from there but it's good to have an idea of where you're staying in proximity to what's going on :)

This part of the island is what you see on all of the Santorini brochures. It's a 30 min drive from Oia to Pyrgos so it's not too bad if you want to stay their for the views & vibes.
