A visit to London

Both my parents are retired. With so much time to spare, they would love to visit me in London one day. With cheap flights and hotels in London, I don't see why they can't afford to come here for holiday. Since it will be summer in London soon, this will be the best time for my parents to come. With lovely weather, they can simply hang out at the park or stroll along the Thames River. My parents will need a hotel near to major tourist attractions in London, namely Tower Bridge, London Eye and Buckingham Palace for their conveniences. Moreover, with cheap hotels and so many things to do in London, they can easily stay here up to few months. I've even organised their travel iterniary !
