Thanks guys!
It seems the accessibility of the subway system is not great considering how new the system is - I think it would be challenging with my stuff. I have a rollaboard and a 22 inch suitcase - I can't drag both of them up or down the staris but I can pull both OK. I don't have the final weight yet as I have not finished shopping
In SFO, I have no problem dragging them through BART to go to downtown. Here, between the accessibility and the crowd, I think it is just asking for trouble. (On top of that, the bags need to be X-rayed going into the subway system.)
I took the #2 train today. There is a standing area in each car for people with suitcases. So, it would not be bad once I am on the platform.
Since the point is really to try the maglev, I guess I will take the taxi to the MagLev. I am going to see where the New World Mall is.
Thanks.
