Just to be 100% clear, when you reserve a time for Eternal Bonding, does that mean it is going to be like XI, where only one wedding can happen at a time, and as such, only so many reservations can happen at a time? Or can an unlimited # of weddings take place at the same time?

I'm confused because the offical site says
Please note that venue reservations are made for two-hour blocks on a first-come-first-served basis
Does this mean that Platinum players effectively do, in fact, get to pay to win weddings (as absurd as that sounds)?
