I will be arriving at LHR before the sun rises I am sorry to say. After it appears – the sun that is - I will begin touring London. On arrival my plan is to collect the baggage then stay in one of the lounges with the baggage in order to eat breakfast and take a shower until a reasonable hour arrives. After examining the maps of T5 it appears that the arrival gates, baggage claim, and lounges are all within the same secure area. Is this correct?
