Haven't had a family room, but have stayed at the Marriott Heathrow and Marriott Slough Windsor, both lovely. Have also stayed at the Thistle, good but not quite as good, and finally Le Meridian which was my favourite. Next week we could only get reservations at The Holiday Inn Ariel so I'll find out what that is like, but I'm not sure that it will match up to the others. Carolyn
