I liked Rotterdam (run and city) - had a real buzz to it. The city is ethnically diverse, very `young`, lots of good restaurants (smart and less so).
Don`t know about the hotels but I got a stunning Air BnB flat which was as cheap as chips.
The race was good - I found the underpass at @ 16 miles I think a right bugger. The sort of `hill` you wouldn`t notice on a 10 miler but at 16 mi in a marathon it really knocked the stuffing out of me.
Can`t remember the baggage situation (ran in 2014) - but my apartment was 1/2 km from the start so it wasnt an issue.
I think it`s very unwise to simply write off a shoe (or to say that it`s the best thing since sliced bread).
I ran (trained and raced) in Lunaracers (in various iterations) from 2008 until 2014. They were - for me - undoubtedly the best racing shoes I had ever used (and i`ve used quite a few in a running `career` spanning 40 years). Quite a few people shared/share that opinion. That said,a number of people really didn`t like them.
I preferred the older models (lighter) but the new ones were pretty good too.
Old age and dodgy knees prompted me to change to something more protective for training (Hokas) - but I still race in Lunaracers or Flyknit racers.
I guess sometimes you just have to try (potentially expensive - and I`ve certainly made fair few mistakes) but I wouldn`t write of a well regarded shoe on the basis of one - or even a few - opinions.
