I'm going to visit London for two weeks in March 2013 and will be using my Hilton Honors points for a hotel. There are so many Hilton-affiliated properties in the city, it's hard to decide which one is best. Four look pretty good to me: The Trafalgar Hotel, the Hilton Paddington, the Waldorf Hilton, and the London Hilton on Park Lane. I will be using the hotel as my base for visiting London and taking day trips outside the city. Do any of you who live in London or who have visited have any recommendations for me on Hilton? Thanks so much for your help.
