No, we haven't gone. We wanted to, but the cost just meant we couldn't make it work and now our kids are virtually in their teens so I think we've missed the magical boat for this. If anyone can afford the cost, I think its a worthwhile trip for the memories. Just a bit hectic i've heard given how much you have to cram into 1-2 days, alongside the plane journey too.
If I see any tips from some of my IRL people i've grown up around, i'll share them here.
