I don't think they do. At the entrance of Fujiyama it said you can't ride if you don't fit in the seat (or they can't close the bar completely).

Of course, Hidden Tips: When you already inside, there is a few attractions who have a ling line, you can download the disneyland app to save line seat (looks like fastrack line) so no need have long queuing (should register first with Japanese name, translete by google)

Hello. You can buy as many passes as you wish. Cheers!

We did not purchase fast pass tickets & did all four screamer rides in the morning

We went in off season, bought tix on the day and couldn’t get priority passes. The waits were 90 minutes, even for single riders. The people with priority passes only had to wait about 20 minutes..

Я ничего не знаю о Snowtown Yeti, но если ехать в Fuji-Q Highlands, то эта поездка занимает весь день. Я из Токио выезжала в 8 утра, ехать до парка 2 часа. В парке на самые лучшие аттракционы большие очереди и там очень интересно, есть много кафе, поэтому посещение парка занимает весь день. Обратная дорога занимает больше времени, поэтому не уверена, что вы сможете все успеть. Хотя, если вы едете в январе, то некоторые аттракционы могут не работать из-за погоды. И если вы проведете в парке мало времени, тогда, я думаю, можете успеть.

You can never be sure when it comes to the weather. When i came in the rides where down due to frost but opened later in the day. Dont panic if you go and see that, stck to your game plan and assume they will open....unless you can speak Japanese and get a clear picture of the opening plans.
