Hi Synergistic:
Welcome to the board. I do not have information on the non-airline transportation questions for Seven Stars. I do get offers for "transportation reimbursement" at such places as Rincon and occasionally for Kansas City and Council Bluffs, IA all you need to do with those is hand over the coupon regardless of whether you flew, drove, or took the train.
To the extent you take the Seven Stars annual trip to Harrah's New Orleans, you will not be given "folio credit" which is use it or lose it, but will be issued 50,000 in Total Rewards Credits which you can use on that trip for expenses, convert to free play, or take with you for use on your subsequent trips.
