Well, I think I went to the website, signed in. Then went to check manage reservation. When I did that there were boxes with different things, like drink pkgs etc. there was also one to upgrade. When I clicked on that it showed me what I had bid . Also had the modify/cancel button. When I clicked on it this time, it allowed me to modify. At least that’s what I think I did. I was playing around different things but that’s what I remember. I also sent emails but didn’t get any helpful response. Hope you have some luck. I lowered my bid, now I’m thinking that was a bad move.!
