DS1 really wants to go up the Eiffel tower when we're there and I'm not sure what to do. I know May is high season in Paris and it's bound to be a shit fight in the ticket queue and at the lifts. Anyone with experience of visiting May? I'm thinking we may have to just walk up to the first level, carrying DS2, who will be just 3, and accept that we're not going to get any higher ...
