is my itinerary work?
there are some question

第一天未到酒店check in時間,行李可以點放?
第一天行程會太tight 嗎 ?
第二天去windsor ,大約可以stay windsor 幾耐, 在那裡留三個鐘夠嗎.三月eton college 又不開放的.
第二天仲可以加入邊d景點, 好似太少, 因為買左london pass, 想係加入london pass包的景點, 有冇好介紹?
第四天, 去唔去埋stonhenge 好?
去邊個市集( convent garden, camden market,notting hill 的portobello market , borought market),如取捨,去那個最值得
想去吃英式下午茶, 邊到好呀?
如去pub, 邊間好呢?
