Does this mean another round of free ride vouchers?
I am not aware of any free ride vouchers. Full refund of the original purchase and a free upgrade vouchers and discount on Avis IIRC. I am one of those that fall in that category from the first round. My current plan is to hold off on buying anything until they actually start commercial operations. I am not crazy about being the first one on the the first train.
"Although not a true high-speed operation, the Brightline Florida service will surpass speeds of 125 mph in some areas"
No, I think this is just bad writing.
Seems like 50/50 fixed seating is the standard for modern railcars. Probably less maintenance, no staff time to reverse, and no risk of Workmen's Comp claims for wrenched backs.
I don't know about standard for all modern railcars everywhere. But it is certainly a trend in Western Europe. In the Indian subcontinent the trend is to move away from fixed seats towards rotate and lock in position type of seats similar to what is standard in Japan and China apparently. And surprisingly those clever Chinese and Pakistanis and Indians have no problem putting charger connections on rotatable seat arm rests.
Brightline had used the argument that charger sockets cannot be placed on rotatable seats as an argument for using fixed seats. 
My experiences with Brightline between Miami and Ft. Lauderdale (both classes) have been nicer than any Miami airport experiences, including transoceanic first class or the AA flAAgship service, both because of the essential terminal design pushed by airplane geometry and the logistics of boarding a train. The walk from the gates AA uses at MCO to ground transportation isn’t short, while the Brightline terminal is an escalator ride away.
This appears to be a somewhat strange claim. Could you elaborate on how you get from an AA Gate to Brightline by a single escalator ride at MCO please?
Yes,the "AA Gate to Brightline" is probably not what you actually wanted to say, since that would involve exactly the same amount of walking almost as getting from an AA gate to ground transport and then some after riding the APM.
I am sure Brightline tied ground transport like their last mile service will be at the station end. But pickups connected primarily to air transport, for general rental cars and long distance shuttles will probably be only at the Terminal C end. The walk is not all that long, and it will even be quite convenient once the actual connecting walkway is built thus not requiring a walk through a parking lot.
I am planning to take SunRail/Lynx to Brightline for my early October trip (assuming it happens). I have not taken Lynx to the airport in over 20 years so it will be a "new" experience for me. I plan to allow myself plenty of time to get lost and then find my way to terminal C. Once Brightline starts running, I hope detailed directions for SunRail/Lynx riders will be available.
Maybe true in much of the US where we seem to in way too many cases follow, "THIS IS THE WAY THEY DO IT IN EUROPE", but it is not true in much of the rest of the non-European world. Case in point: In my one trip in Japan, on one regular line train, at some point it the route it reversed direction. At that location, everyone in the car got up, rotated their seat and sat back down. South Korea's first high speed trains equipment was essentially French TGV, including fixed seating, only having a different paint job. Initial ridership was much lower than expected, one major reason appears to have been a near rebellion of the female component of the population on the basis of, "I will not sit knee to knee with some man I do not know." I have heard that they ultimately tore the seats out and replaced them with Korean standard rotating seats.
Looking forward to your report on transport from Sunrail; Lynx to Brightline terminal since we will be departing Amtrak at ORL and needing to get to Brightline for our ride to FTL. With luggage it might be better to take a cab or Lyft ride??
Maybe so if there are two of you. Carting luggage to Sunrail to a Lynx bus to the airport may be worth springing for the $25 Uber quotes (on a Saturday). But we’re still planning on Sunrail/bus to the terminal when Sunrail service starts next year to Deland.
I'm picturing in my mind something akin to a scene from Metropolis.
