At first we were bummed because our table was the one of the last tables in the car (there are two sets of tables that run down the sides of the cars) but once we got to our seats we realized how happy we were that we were at the end! They had the tables squeezed in quite tightly, so if we would have been in the middle I think we would have been slightly more cramped. Plus the noise level would have been worse, with tables all around us. So being at the end turned out to be a great thing! We also noticed that if you came as just a couple, you were placed at a table with another couple - unless you paid extra to reserve the entire table to yourself (which we did see someone do).
It was definitely a unique experience - something I had never done or known was an option, so Russ & I were thankful that they let us join them!
