I bought 1 cash ticket (adult) and redeemed for 3 AGR points tickets (1 adult + 2 kids) on the Missouri River Runner. Tickets have been issued from Independence - Kirkwood stations (mailed to us because Independence does not have a manned station.) Trip is scheduled out Aug 11, return Aug 13. Q1: How hard is it to change these tickets to the downtown St Louis Station? Q2: If we DO change to downtown Union Station instead of Kirkwood, how hard would it be to DISEMBARK EARLY (same trip as ticket) at Kirkwood? Q3: If we DO change to downtown Union Station instead of Kirkwood, how hard would it be to BOARD LATER (same trip as ticket) at Kirkwood? I believe the AGR points should be the same (1,000 each way) anywhere along the MRR. I imagine the cash price might be slightly different. Thanks for your help and expertise. Edited to Add: Current tickets are ROUNDTRIP Independence to Kirkwood. Want to (possibly) exchange for Independence to STL.
