Europe in general is a very child-friendly place -- and travelling with kids is relatively easy.
At the Rhine -- i felt it even more -- cos almost every town we visited had a playground located by the riverfront -- while she plays, we can just sit around and relax ;p even the cruise boat had a play area ! considering that our entire cruise journey took 2.5hours (altho we did make a mid-journey stop) kaira was so well occupied she didn't disturb us ;p
on the cruise boat :
initially, i wasn't sure if she can manage the hike up and down Castle Stahleck in Bacharach without needing us to carry her ........ but she did it and was very enthusiastic about hiking ..... hahaha. well, at least it was fun!
here are more photos of her!
