Read Maria’s diary. Tick () A, B, or C.
Saturday 18 July
We left home early in the morning, but our flight was delayed and we didn’t arrive at Heathrow until late in the afternoon. We were really tired, but we took a bus to our hotel because taxis in London are very expensive. When we got to the hotel, we had a rest and then went out to explore the city. We had a quick sandwich in a small café and then headed for Oxford Street. I bought a jacket and some T-shirts. I wanted to buy a bag as well, but I couldn’t find one that I liked. In the evening, we ate in an Italian restaurant and went to a typical English pub in Covent Garden. We met some really nice English people and had so much fun that we didn’t get back to the hotel until very late!
Sunday 19 July
We got up late and had breakfast in a café. I had a full English breakfast, and then I had some fruit. Anna just had toast. After breakfast, we went for a walk around the city. We saw Nelson’s Column in Trafalgar Square, Buckingham Palace, and St Paul’s Cathedral. In the afternoon, we had a pizza and then took a bus to the train station. Travelling by bus in London is a great way to see the sights. We caught an evening train to Stratford-upon-Avon and arrived at about nine o’clock. We went to our hotel and had an early night. We wanted to get up early the next day and explore Shakespeare’s birthplace.
