Dh, myself and DS (will be 34 months at time of travel) are heading to Amsterdam at the end of March. We live in west London so getting to Heathrow or Gatwick is not too bad. Does anybody have experience of taking the Eurostar there? Trying to decide whether to take train or plane, in order to make the journey as painless as possible with DS and fit in his early afternoon nap. Both dh and I have back issues so wary of lifting luggage. Any advice/recommendations appreciated. Many thanks!
