So DW and I have been Mlife members for several years. Essentially we have used my card to establish a Gold Level standing. When we went to the Aria recently our host told us that DW should get her own card as it will help with getting better comps. Can someone explain to me how that works please? I thought that if we had $1500.00 to spend daily it would be better served on one card than spliting that $1500.00 amount two ways by using two cards??
