We've done Legoland Windsor twice now and stayed in Windsor and then Slough at a Travelodge/Premier Inn. It's a pita from Slough as we are on public transport. It's not horrendous but not ideal either. We would love to stay at the hotel but is it worth it? Particularly is it worth the themed rooms if you choose the ninjago ones? Ds is 10 and is a huge fan of ninjago. They have a sale on at the moment with the second day in the park free but it's still over £400 for the two of us! The cost isn't an issue but whether or not it's worth the price. Billund is out of the question for now.
