How much time should I leave between consultations?

I’m planning revision eye surgery because of multiple creases, and I’ve even made a list. For now I’m looking at three places, and a lot of people said the list looks good, so I’m going to try booking them like this, but how much time should I leave between consultations? ㅈㅇㅈㅇ - ㄱㅂㅇ ㅌㅇㅅ - ㅇㅅㅊ ㄹㅎ - ㄱㅈㅇ I’m planning to book them like this, and the route is really convenient, but should the gap between consultations be one hour? Two hours? About how much is best?? And it’s possible to visit all 3 places in one day, right? For those who’ve been to consultations here, I’m also curious about each hospital’s consultation style ㅠ
