In the hopes of keeping this about the new bugs/technology/issues, and not the neverending debate...
I'm concerned about the split-stay aspect. It isn't clear to me that if "length of stay" is just a 14-day mug, since it says that it can be for longer than 14 days...I've got a split stay coming up - no idea if this will be in place yet, but I'm not going to shell out $18/person twice...
I'm sort of wondering why they didn't add this as a MagicBand/MM+ profile feature, rather than add chips to the mugs...
