In the planning stages of a two week international trip to selected cities including four days in London during May 2011. Will be 4 senior adults, no major handicaps........... Will spend time sightseeing Buckingham Palace, Westminister, London Eye, etc. Or might consider escorted day tours.....comments??? Will arrive from U.S. to Gatwick Airport. Would prefer lodging in good area with small to medium non-chain hotel with pub, maybe restaurant or local restaurants, shopping, etc with transportation options throughout city. Willing to spend 175 pounds per night, but must be something special. Would appreciate all help. Oh, will be leaving London via Train to Paris. Would appreciate all comments recommendations.
