So I've never stayed at the Dolphin so can't weigh in on that. But we LOVED YC when we were there in August of 2018. For a short trip, I'd not care, but for a 6 day trip, I would probably pay the extra $$. Depends on if this is a big trip for the year or if it is one of many. In our case, we are planning to probably do 3ish big Disney trips in our daughters' lives (6, 10-11, and sometime between 15-18) so for those, we will probably (not to an extreme degree and depends on life at the time) spend a little extra to do what we really want. In this case, I would hands down do YC. But I know people like the Dolphin too, and it is literally next door to YC so the location (which is great) is the same.
