I unfortunately got caught up in this coming back home, I was leaving at 7.30 and the fire begun at 5.30 !!. Eurostar were great though and very helpful. We were delayed for 24 hours and put up in the holiday inn and then flown home!
It may take a bit longer to get there but everyone will still get to the magic, getting home they're very organised and yes there may be some queueing involved but nothing to bad. We're englsih and use to queueing!!!
Just take some extra baby milk and nappies just in case if needed. They sorted everything else
