Interesting response. I will tackle a couple of things together.
Thanks for your reply. Everything you stated is a valid issue. However you did not check with the organization web site. The train is fully sold out, both on the game designer web site, and on Amtrak web site.
I'd like to tether this with my previous statement.
Indeed, groups have a certain amount of time to preserve their space. Maybe they won't even show and all the space will be released.
While you'd like to use the term "sold out," I prefer to use the term "reserved out." This is because as we've discussed on the board about groups, there may be a hold on the space until the numbers are settled. The numbers are not settled until payment is rendered. It things aren't settled by a certain date, the space will be released. Perhaps that date hasn't occurred yet.
Denver is a short platform but looks like three additional cars could be added in October when the AU gang was in town. It does have the ability to host PV, and the second track. So yes it's a pain by design, but not a excuse.
Even if a unstaffed Lounge car was added just for space, some of pax might not notice but some may. Good will for a group travel with lap tops that are networking. (Both social and work related)
The other issues is this middle of the winter run using the short off season train set or the full summer mode length.
You're of course saying this without knowing if they are using an abbreviated consist(which judging by the numbers, I'm willing to say that is not the plan) or knowing how many people are actually currently considering the trip. As such, you don't know if they are not only bringing in an extra lounge ( or two), but an additional diner to feed the amount of people that are traveling for three days. Remember, they did just that in the thread I linked above (which had a similar amount of people scheduled). This would naturally impact operations at a place like Denver. That is more than a "pain" or an "an excuse." It is indeed an operational issue. So, again adding additional equipment might not even be feasible.
However, let's say that it is and we have two more cars to play with. Assuming that the group didn't ask for exclusive occupancy, they are traveling end to end (and then some I think.) All you need to do is staff the train for the group and make the usual recrew/servicing stops (just as they did in the thread above.) How much additional revenue will you capture and how much additional staff will you need to accommodate the additional riders. Will they even show up since as you've previously stated, it is the dead of winter? Perhaps, they are looking at it and saying "this train, which is a big money loser is completely full. It is one train, so we'll leave it sold out and stay ahead of the curve." Deadheading equipment for three days still costs money. That of course assumes the equipment couldn't just stay in California, to which I say perhaps it can. I would probably use the CAL pool and deadhead the equipment out to CHI for the beef up so when it gets back to California, it settles back in.
I can only speculate about the contents since there are a many variables and this trip is still far off. For all we know, more equipment will get added. They added more equipment to existing trains and eventually more trains to support the Million Women March. For all we know, some of the members of this group will not make the trip and that space will return to inventory. We should probably wait until the end of December and see how things are really shaking out.
