It sounded like you had a great time overall. I'd love to hear what you liked and didn't like.
I'll eventually get to
Disneyland Paris in my trip report but as I'm only on Day 6 of the 19 day trip - it will be a while as I need to get through all of Brittany, Normandy and Paris first! I just finished all my Versailles & Loire Valley adventures.
What we liked:
1) The 5k & 10K Courses. They were mostly in the parks with very little backstage overall. It made the course fly by!
2) The location of the race end in Walt Disney Studios in comparison to our hotel (Disneyland Hotel) Yes, we had a bit of a longer walk than some of the other hotels to the start line but it was great when you are in that post race zone where all you want is a shower.
3) The crowds at the beginning of the race as you head through Disney Village. It was a different feeling to have that much cheering at the start of the race versus what you get at Walt Disney World. It really energized me.
4) Squeeze bottle tops for the Powerade (I know a weird thing to like!)
5) The chips given with the food boxes. I'm going to stalk my local European market to see if they can get me some of those!
6) The rides. Phantom Manor was the best version of the Haunted Mansion I have been on. It really felt like a story was being told and I like how the graveyard scenes actually felt like the ride was appropriately placed within Frontierland which originally seemed weird to us. Their hyperspace mountain was smooth but more adventurous. Ratatouille made me excited we are getting the ride although I hope ours will seem less fuzzy on the screen. Crush's Coaster was a lot of fun too!
7) The pre-show. While it kinda felt like a talk show more than a pre-show, we really enjoyed the difference in it. They had someone on to talk about the design process of the medals, commercials for Disney+, no horrible jokes.
8) Disneyland Hotel. Something about your hotel being over the entrance of the park just feels special.
What we didn't like: (I didn't run the half but my husband did so the half comments are his)
1) A portion of the half course had to pass the Dinotopia props three times.
2) At the end of the half, if you have challenge medals, you have to head back to the expo to get those medals. Either we didn't research enough or it was something that changed from previous years as I don't recall reading about it. My husband was not happy that after running 13.1 miles he had to walk around a mile (or what felt like a mile) to go back to the expo to get his challenge medals before walking back to our hotel
3) The lines at the expo and the inefficiency of them all. We had pre-purchased photopass for the run+rides. The pass was good for up to 3 bibs which was perfect for our use. We spent at least 40 minutes at the expo getting the card so it could be activated. I just feel it could be better managed as maybe I'm spoiled by WDW's system. We are also not sure how many photos we got as it didn't seem the photographers were really taking that many photos unless you stopped in front of them. I will go online to download the photos this weekend and see what we ended up with.
4) The food quality. I realize we went to Disneyland Paris after having two weeks on a Tauck Tour and other amazing meals on our own but the food in the table service restaurants felt overpriced for what we received. I'm not sure if we had done Disneyland Paris as the start of the trip rather than the end if our opinions would have been different though.
5) Course etiquette during the 10K. This is a mindset change versus the WDW runs. In Paris, the 10K is not timed and thus is viewed as a fun run & the corrals for the non-challenge runners are very random. If you are trying to run for time, you will get frustrated. My husband was. His corral was actually behind mine and when he caught up to me, I could see it on his face before he went ahead.
6) Guest behavior. We experienced some really rude behavior at the parks that we hadn't seen elsewhere on our trip even in more crowded locations. I got repeated elbowed in the back in line at Pirates to the point I kept moving to avoid it but he kept adjusting to continue it. It was probably the only instance in our trip where us not speaking French hindered us in communication and my husband did sternly comment to the guy but confused looks occurred and my back still got hit. I was glad when the ride got shut down and we could get out of there! Probably a freak instance. We also ran into way more smokers here than anywhere else in France but we knew that would be the case since they don't really respect designated smoking areas.
