Hi Erika!
The new Tinkerbell 10K race looks so fun! I am jealous that you will be there:)
You will pick your packet up at the Health and Fitness expo located in the Disneyland Hotel. Here are the hours for the expo:
Tinker Bell Half Marathon Weekend Expo
Disneyland Hotel Exhibit Hall
2:00 p.m – 7:00 p.m. on Thursday, January 16, 2014
10:00 a.m. – 7:00 p.m. on Friday, January 17, 2014
10:00 a.m. – 5:00 p.m. on Saturday, January 18, 2014
For the Pasta in the Park Party, the tickets were sold in advance and are already sold out. If you purchased tickets to this party, then you will pick those up at the expo as well.
Theme park admission is not included with race registrations, so if you want to visit the parks, you can buy that separately.
I hope this helps! Please let me know if you have any other questions and good luck at your race!
