I want to book the Philadelphia Marriott and am ready to commit, but an wondering wether the rate can be bettered.

i used to do very well with LNF but for the past few years have had nothing but rejections, mainly claiming currency variations (by 10%??) or claims that the site I located is some kind of club.

So, to you experts out there, looking for a rate for the Philadelphia Marriott Downtown 30th Oct to 3rd Nov for a twin bedded room, current advance purchase rate is $696 (not inc taxes)
