Hey there! Yes, I'm double checking because the same year you switched from POFQ to WL, I kept my old tags on and the ME people at the airport told me I didnt' have to change anything on the tags because it was barcoded and it would go to the WL because it's what is in the system...and of course, we checked in to the WL by noon and went to the MK all day and when we returned at seven pm...no bags. I went downstairs and they called around and they had been sitting around POFQ all day!So we couldn't go swimming or anything that first day because our luggage didn't show up til first thing the next morning. I wanted to make sure that didn't happen again!
Just cross it out, write Poly and be sure they note it at the ME counter. We checked in to WL, headed to DTD and when we got back to the room....BAGS. It will work out. Good luck!
I almost have all of our little travel toiletries, there's a little group of them on my bathroom sink, a reminder of how close we are (Feb 2 - 7). Bought some new athletic shoes, and some for my DD, who has grown out of her other shoes again! Gonna get the suitcases out of the attic next weekend!
