Hi Folks this is my 1st trip to DL, and I am a WDW vet. I will be arriving in August and can't wait to experience the original park and 60th anniversary celebrations. I have a question about the glow ears. I bought my family the ears on a trip back in November 2013 at WDW. I've brought them back to get my $s worth this past July. I was hoping to use them again out in DL, but wasn't sure if they were compatable with the west coast parks? If so, do they sync with the new 60th celebrations too? Thanks for your help.
