I purchased the Memory Maker for our upcoming trip in May. Can anyone tell me if it can be "active" on everyone's magic band in our group (Me, DH, DD & DD's BF)? We have two different reservations because we needed to book two rooms. We aren't planning to be together for every moment of out trip. Can my DD use the Memory Maker if I'm not with her? How does it get linked? Thanks in advance for your knowledge & help.
