Might be advantageous to allow some limos to arrive before the others. Jack and Fubuki have shown a pretty strong dynamic together, but I think we've pretty much exhausted the conversation in the limo.
I'd say that while Emily and Ryo have their duel, and Aono and Miwa chat in transit; Joseph, Fubuki, Kenta, and Jack should arrive at their destination and wait in a large reception hall of sorts. Food and drink, scantily clad waitresses, and all the Vagas ilk. Introduce your wandering hologram concept at this point as well. The four of us then chat while waiting for the other duelist and the Khan to arrive.
I say this all in the name of keeping the RP moving forward. There is no need to keep half the cast waiting, but we also can't let them get too far ahead of the others.
