My mother and sister are thinking of flying from Spokane to St. Louis, get from the airport to the Gateway Transportation Center, and then on Amtrak 306 to Bloomington, IL. I know the Metrolink has a station at Lambert and I know it runs very close to the Transportation Center with its Civic Center stop. My question is: where and how far in relation to the Civic Center Metrolink stop is the Amtrak portion of the Transportation Center? I know it's not far at all (within perhaps a block) but my mom is a tiny bit restricted in mobility and can't walk much more than that without stopping to rest, especially with luggage. Again, I know it's not far at all, but my mom and my sister (and me, for that matter) are not at all familiar with St. Louis, and I'd like to know, on their behalf, the particulars for them. Thanks!!!!
