Thank you all for suggestions on saving $ on the Mustang convertible out of BOS over Memorial Day! I have one more quirky Hertz website question though - the RQ: HFC1 isn't working for FUN cars in BOS, and Hertz won't answer e-mails on this - any ideas as to why? I'm reserving for a week and following the rules stated. Thanks (as always!) for your help! =) ~ Julia
