REVEAL
the cheapest parking seems to be at the domestic parking.
when you double up with the 10 days @ $8 a day = $80 less 30% = $56
the international Parklong does accepts the code but you can't double up the code and the cheaper 10 day rate (so cost for 10 days will be ~$115. compared to domestic- but you can easily get the free shuttle in between).
the airpark for 10 days is $55. - but not undercover and you have to catch the shuttle (which is pretty regular -I've used it twice in the last 3 months) - link to airpark site - you can't use the code through this site though.
