They are turning it from a nice family hotel to a kids hotel that adults will hate, it looks like a creche. With no class at all. I guess they think their guests are too stupid to appreciate subtlety in design and need to bit hit in the eyes with FUN FUN FUN, just in case they weren't sure what they were supposed to be having.
Why? Why spend money on making things worse? It angers me more than spending no money and letting things rot. It clearly isn't being done on the cheap either, it just looks like it is because of the atrociousness of it. Who signs these things off? Fools.
