We will be in Santorini for four days in mid-May, staying in Oia. We'll have a car so no problems with transit. Assuming we can only do one or two in each category of the following, which would you recommend:
WINERY. We are looking for a nice view, a tasting room, perhaps place for lunch. Tour of the vines or vats would be a nice extra. Santo? Venetsanos? Sigalas? Other?
BEACH. We want a nice place to sit, relax, stare at the sea and maybe even put our toe in (if warm enough). Lounge chairs and umbrellas would be nice, but we don't want crowds or partying teenagers. Red Beach? Vlichada? Koloumbos? Other?
CALDERA SUNSET CRUISE. Prefer to leave from Oia / Ammoudi, but not necessary. Want to see the volcano, hot springs, Thirassia, have dinner, see sunset from boat.
