I have done 2 Princesses as well and getting ready for my 3rd.
Just back from my first Tink.
I love Tink. I like Princess, but LOVE Tink.
1- loved being so close to the start. I stayed at PPH and walked out my room to the start. It rocked. This hands down was the best start for a race for me. I HATE the Princess corral walk- holy cow. It's insane. But this was just awesome.
2- course was GREAT to me. Heavy in the front end with the parks. I felt like I could party in the beginning and then get to business on the back end. The first 6 miles just flew by for me. That's similar to how I feel with PRincess too, but the miles leaving MK back to Epcot seemed soooo much longer to me than the ones in Anaheim. Part of it was the buildings and neighborhoods to look at- plus more crowds to cheer us on. And school bands and stuff. I liked all of that a lot.
The course is also MUCH flatter than Princess- IMO- which gets big points from me. A few hills and the worst was at mile 12 (it was similar to the up and down you do by the contemporary on the Princess course) But over all, the hills were at the beginning (again- I prefer this to the Princess and the last 3 bunny hills at the last 3 miles!)
3- tons of women and a sea of green! The guys were fast though- they caught up to corral B pretty quickly. But not too many, so still have the girl power vibe like Princess. Just more green and wings, less tiaras.
4- logistically again- great. the end finished right behind my hotel. I was in my room in 10 min from finish. LOVE LOVE LOVE
I'm really thinking I am going to change my annual trip from Princess to Tink. I liked it a lot.
The weather was also better- less humidity. It was PERFECT for the run. 0h--- and it started earlier. not sure if they will keep that but I LOVEd the 5am start. Get to business and get out! lol
