Hmmm. Guess I could've waited then....I had tags made at PetSmart.

My 4yo DD is thrilled with hers (pink heart). My 11yo DS wanted a blue one to go with his sneakers (I'm threading them onto the first pass of the lace since I don't trust either of them not to lose them otherwise) but all they had in blue was a dog bone! Oh well. Guess we can always get them a fun one while we're there too!
On a side note, I made ID cards for them with just their first names, "If I'm lost please call... (our cell phone numbers)", and "We're staying at The Polyenesian Resort" on one side and their favorite character on the other side. They're going to wear them on their lanyards in the press pass holders I got - character side out. So they'll have picture IDs on them and with the contact info for my husband & I but it won't be announcing their names to the world either. My husband & I are going to carry copies of each of their IDs too so we'll have pictures on hand in case they get lost.
And yes, I confess, I ordered those safety tattoos too. Yes, I'm a little over protective...but I've worked for the Dept of Correction for over 20 years and have dealt with some pretty scary people! I'd rather my kids have 3 different ICE contact methods on them than have them disappear and not be able to reach me. So, 1) ID card...if they lose that; 2) dog tag...if they lose their shoe (?) or we're at Blizzard Beach; 3) oh yeah! my tattoo!
And yes, I confess, my husband thinks I'm nuts.
