The last time I went was in 2017 when Magical Express still existed. Going with some friends in September, but we're coming from different places and will be landing at the airport at different times. Is it possible to check Uber/Lyft when we each land to see how expensive it is and then, if Mears is cheaper, go over and book that instead, or do you have to book Mears in advance in order to use it? For example, I have Uber One, so I usually get a bit of a discount except at super busy times, so I want to check and see if that would end up being cheaper than Mears, but I won't really know until I get there.
