The stroller was found but it took some work. He is the story and some information so it doesn't get lost agian.
I had PMed the person using the stroller directly ahead of me in January to sort out all the details. They had let me know they were using the stroller until 2pm on 2/14 and leaving early 8am on 2/15, staying at the POP. I told her if she was done with the stroller on the 14th I could pick it up on the 14th after the HDDR-10ish. She agreed, I had given her my full name and my cell number, she gave me nothing. A week or so before our departure I PMed her again and recieved no reply, while I was slightly concerned, I thought they may be traveling and not have internet access.....things were going well with the swap. No worries.
So we arrive (Sat afternoon instead of Fri night) go to HDDR then Hubby takes kids back to SOG, me and 13ds hop the resort bus to POP. Luggage folks have no stroller in my name, and invite me back to look (very nice), 3 strollers no Mac. So now I am wishing I have previous stroller users full name, I could check at the resort to see if they are here, have the stroller...something. But back to SOG I go and the boards, luckily I was able to post (we were using an aircard for internet and cell reception was good, but it kept droping the internet) so I posted and Pmed the previous users and eyore!
Sunday @ MK, no stroller, we did ok
Monday @ AK no stroller, still ok (checked with SOG for spare stroller, nothing)
Tuesday @ HS no stroller, still ok but get phone message on Cell from the stroller swapper before the person ahead of the person ahead of me with magic LG # (I believe this is the number for the transfer from BC to POP) I call BC with the number, they take the LG number and my cell number) within 2 hours they call me they have the stroller and would they like me to transfer it to my resort, it will be there by 4!!!! and it was!!! And just in the nick of time, because my dear, too big for stroller kiddies, petered right out.
I left the stroller at the POP with the next person's name and arrival date on it. No LG number because it's not being transferred.
So my best advice is confirm information with the person ahead of you and the person ahead of them, and keep all paper work.
Update on the stroller, it is still in good shape, showing some wear, and the light color is showing the heavy use, but it is not bad. All parts in working order. Macs push so nice especially with bigger kids in it (i have a 40 and 45 pounder) I tied bright green and white polka dotted ribbon on the handles so we could find our strollers in the mass! (we brought our 13 year old mac stroller with us...it's still a great stroller.)
Thanks for all the help and
