Just wanted to post a message to all those parents who panic at the thought the kids are going to disrupting other guests.Travelling alone with my son, I stayed overnight at the grosvenor square marriott, London UK. Whilst using the executive lounge, the hostess was ever attentive to our needs. After 20 minutes of TV, my 3 year old started getting a little restless. I was overjoyed when the hostess appeared with a bag of goodies for my son incuding a childs guide to London, jelly beans and colouring books/pens. This really made our stay. Highly recommend this hotel for this (and also location).
