It depends on volume and how big the groups in front of and behind you are. I rode it pretty much all last week, only once was another group put with my family of four. When my wife and I rode just the two of us, they put another couple with us on three of the four legs.
We were about 2/3 with just the 3 of us and 1/3 with others. It’s really not that big of a deal riding with others. We were never paired up with more than 2-3 people. There was always plenty of room to sit and spread out.
Stayed solo at CBR. Only had to ride the skyliner with others maybe 3 times out of a dozen trips? I'm sure even then if I said I was opposed I could have ridden alone.
Stayed as a 4-some in November and maybe three did we travel with others. All other times we always seemed to get a gondola to ourselves and we rode the Skyliner a lot. My guess would be at least 15 times during our stay. Never got old. We even changed existing breakfast and dinner reservations so we could use the Skyliner to get to our new chosen restaurants. Loved it.
