Yep we love a city break.
Was in Krakow in March and away to Prague in October
Until recently, because we had allowed our passports to lapse our breaks were all UK - York, Edinburgh ,Ayr, Glasgow, Newcastle, Liverpool - we are in NI so a flight required no matter . And under-seat bag is included in ticket price and is plenty big enough for 4 or 5 days
We can easily do 20k steps a day or more
We have coffee in the apartment in the morning, then head on out. Stop to eat when hungry , stop for a coffee or beer when tired
I research like crazy before travelling. I make a list of "must sees" and use google maps to plan what and when - so we aren't walking back and forth. So we are in an area and we see what we want to see in that area. I will also have a short list of bars and restaurants in each area
I also research the public transport system- knowing what tram or metro station we need, how to buy tickets etc. Anything that may be difficult to get tickets for whilst there, I book before hand
We plan on doing two pay in attractions/exhibitions a day and taking in the free sights as we go
We also have Bolt downloaded so if we are knackered and the far side of town from where we are staying - a taxi is with us in minutes. Im more of a walker then DH so whilst I can keep the pace up all day, I make sure we stop every couple of hours to sit with a beer or coffee
Whilst it sounds regimented, it's not. We wake, see what the weather is doing and decide then what we are doing that day. Some days we are away out at 7am, others it will be closer to mid day
And some cities have so much to see and do its madness to try to do everything in a couple of days - been to Liverpool 4 times and still not covered it all - but that's ok, means we get to go again :)
Good shoes are a must on a city break , esp those cobbled cities. And layers. Being uncomfortable , be it feet hurting, or too hot or cold or wet makes for a miserable tiring trip
