I also was annoyed at the paltry 50 miles a day (plus the dumb FF tax) so I started putting my "miles" on my Hyatt Gold Passport. Apparently there's no tax on hotel points. And I was getting 250 points per rental, which is like spending $100 at Hyatt to get that many points. There was a double points deal earlier this summer w/Avis. Downside: it takes forever for these points to post (Do I blame Avis or Hyatt?)
I signed up for Virgin's FF program and got a number, but since I didn't take a flight yet did not receive the top secret Avis rental code. Does anyone have it here? I have been too lazy to ask/search on the Virgin board
