请教维也纳公共交通票

尊敬的游四海旅游大神，
我们有四个人，在维也纳住三晚。在做维也纳公共交通功课，有打算每个人买72小时通票16.5欧。在介绍中看到还有一种选择：8-day-ticket Vienna（就是下面列的介绍），38.4欧，看介绍我理解意思是相当于一次买了8张日票，只能从打票时开始用到第二天早上凌晨1点。多个人可以用，有8联的，每用一个人就撕一张下来打票。请大神帮看下，是这样吗？

8-day-ticket Vienna




For persons staying a longer time in Vienna, but not using public transport services every day.


Valid on all public transport services in Vienna


Valid from the stated date and time until 1.00 am on the following day
Validated for any eight days, not necessarily eight consecutive days
Valid for several persons travelling together (simply validate one strip for each person)
8-day-ticket is transferable
Purchased tickets will be delivered by registered letter.


看了一堆的票种，有点头晕。请您建议下我们四个人在那里呆3晚，买哪种票比较合适？非常感谢！
