Hi Ronda!
Congratulations on signing up for your first race! The 10K race is a great distance, and there is no better place to run than at Disney!!
For the Tinkerbell 10K, your family will definitely be able to view you at the finish line. They don't have the course finalized just yet, but most of it will wind you through the Disneyland Resort area. It's going to be AWESOME! I would keep checking back on the
Tinkerbell Half Marathon weekend website for more details and spectator viewing areas for the 10K. There may be some great viewing areas in the Downtown Disney area, as well.
As for the chEAR squad packages, those are mostly for viewing areas on Sunday for the Half Marathon. You can certainly sign up for the Bronze package to receive emails, etc., but your family won't need any kind of package to access the race. (Half Marathon spectators don't need to sign up for a package either, the packages just offer special viewing areas and other perks for those that do sign up)
Closer to race time, there will be a Final Race Instructions booklet that you can download from the website and will also be available in hard copy at the expo. It will have all the details about transportation, spectator viewing areas, etc.
I hope this helps! Please let me know if you have other questions as you get ready for your big race!
