Hi, i'm looking for a place to stay downtown st. louis april 1/09. i'd like 4* because it appears you can secure 4* lodging fairly cheap. I've never used priceline before. how low should i start bidding? it also appears to be a plethora of rebid zones to use since there are no other 4*? because of this, how large should each increment be? when i do get a room, will there be extra charges for parking, or resort charges, or anything that i should be aware of? also, i'm curious what order i should go in - if it matters at all? it gives me 9 choices of zones, with #1 being downtown. so, 1, 1-2, 1-3, 1-4.. 1-9 then 1-2-3, 1-2-4.. 1-2-9 then 1-2-3-4, 1-2-3-5.. 1-2-3-9 ? any help will be appreciated. i've tried to read as many FAQs and help threads as i could, but i may have missed something - there is so much info!
