Have a look at their website for info and rates for their horizon rooms. We are going there in August.

Think it turns out about an extra £30 a night for the room- its well worth it- your breakfast, afternoon tea and drinks until 7 or 8 pm. We were asked if we wanted it when we arrived at the hotel and thought it to be a good deal as breakfast was roughly £8 each. We had not upgraded before we went. The view to the twin towers from there was great. You don't have to take your breakfast in the Horzon Club but are entitled to go in the other restaurant (which had a chocolate fountain ).

Hope this is of some help- a lovely hotel.
