Hi Ashley!
The chips they will give you are he black ones you can view down towards the bottom. They will give you a plastic tie to attack it to your shoe. I typically would weave it thru my laces and thru that little loop on the shoe tongue that the laces go thru. Going thru that loop is probably all that is needed but I'm always paranoid

They will have a volunteer after you cross the finish line that will snip the tie and take the chip off. So probably better to not do to much lace weaving LOL The yellow ones are personal chips.

Which corral you are in will be listed on your bib. Looking at the Fond Memories and Crossing the line it looks like the Corral letter will be up in the corner.
There is a corral map and finish line/family reunion area on the the final instructions. And they will probably have that in the Princess Handbook they will handing out. If someone didn't get the email with the Final Instruction link on Friday drop me a PM today, I'm back to think I'm sick and not going anywhere
When you go to packet pick up. They will take your waiver and I think mark it and give it back to you. They will have you sign next to your name on a master list they have. you will intial that you rec'd your chip. They will give you your bib and a champion chip envelope that I think is like 5x8 in size? which will have the chip in it along with the plastic tie for the chip. DO NOT LOOSE THIS CHIP they will charge you I think $30 or something for these. I always check to make sure the plastic tie and chip is in there and fold it over a few times so not to lose the chip. Did i mention i'm paranoid LOL
Take your chip envelope to the table (the volunteer who gave it to you will point this out and if not ask) where you will wave your chip over a sensor and verify your info on the computer screen. (age/name)
Then you go to the goody bag area.
They will have given you your Waiver back this you take to the goody bag area where they will take it and look at the shirt size you ordered and give you your goody bag and shirt and THEY keep the waiver.
The layout of this can change but basically 3 steps. Most likely the bib/chip pick up will be by bib #. Next verify your chip info is correct. Pick up your bag/shirt. Shirts/bags are laid out by shirt sizes sometimes depending on how much room they have.
then it's off to shop the merchandise and all the wonderful vendors.
OH!!! Make sure the goody bag has your safety pins for attaching your bib. Frankly if you have them at home I would toss some into your checked luggage because I didn't get a single safety pin in January LOL It happens.
OH!!! Pre-ordered Pins, Party tickets, Runners/Spectator Retreats are typically another line. Actually I think all these items are 1 line.
I typically have safety pins baggy with me so I will try to remember to bring it to the POR retreat as a back up just in case
How's the packing going everyone?
