@TizerorFizz I know...it's baffling!
I have travelled extensively throughout my adult life and have been to a lot of big cities. I can honestly say I have never once come home saying I HATED every single aspect of it and that my home city was far superior. It's so incredibly weird to me!
I travel BECAUSE it's going to be different!! I research and plan and read blogs and reviews and it's all a bit part of the experience of travel to me.
I think perhaps some people might be used to going to places that are predominantly centered around tourism so you arrive and it's all right there in the resort or whatever, there's no working at it to make sure you get the best out of the trip. And then if they travel to a large, working city it's a bit of a shock that you have to navigate to find the stuff you want to see or do.
In all our years of travelling I've only had 2 experiences of coming away feeling like I had not seen or experienced the best of the place - both times when dc were at the toddler / v young child age. And in both instances I knew that it was our own fault, through circumstances that we didn't enjoy it as much as we'd hoped. In one city I got very ill and required a night call out from a doctor and I felt under the weather for the rest of the trip plus we misjudged the accommodation and we were too far from the old centre.
We returned to that city 8 years later and had an absolutely wonderful time, as I knew we would and I am so glad we went back.
The other city was Toronto, we were there for 3 weeks but the dc were at a bit of a hard age and we felt a bit like we missed out a huge chunk of the experience by not being able to go out much at night as they needed to be in bed etc. It was what it was, we made the most of it but if the opportunity arose to go back I know we'd now have a very different experience.
I also don't love visiting cities in the middle of summer as they get too hot and feel over crowded so we tend to always aim for Autumn / Spring though I am very partial to a pre-Christmas city trip and have been to many cities in the lead up to Christmas - NYC, Prague, Budapest, London, Dublin, Belfast, Berlin and we found much to enjoy in all of them.
Open minds and good planning are the essentials for successful travelling
