I'm leaving for DW in 5 days and I'm pregnant for the first time. I'm super excited about it, but I'm starting to have issues standing for even short periods of times (i.e., 15+ min.) because my legs and feet feel so swollen. I normally don't have any problems walking around the parks for hours or standing in line, but I'm concerned about this trip now. Any ideas for tricks to help circulation while standing in line without bothering people around me? I usually avoid lines longer than 25-30 mins anyways. Thanks!
