About a week ago my classmates and I went on a school trip to Peschiera del Garda for five days. The journey was fun: we sang and played for the entire duration of it. We arrived at the hotel at 8 o'clock; it resided in a beautiful area close to Garda's lake, but it was full of toy frogs of all kinds of sizes.(Are you sure that their meant to be toy frogs?)
On the second day we visited Verona and went to the House of Juliet: we saw the most famous balcony in Italy. There were a lot of padlocks. On the third day, after we visited the Made Expo, we went to Milano. On the day the following day we went to Venice and saw Piazza San Marco the Ponte dei sospiri and Ponte Rialto. We also went on a veneciant boat which was charming. Finally on the last day we came back and on the return journey we visited Rimini.
I corrected a few mistakes that Suresh made, just minor lapses in grammar. Although for several bits of your piece I was a bit confused about what you wanted to say, e.g the bit about toy frogs. Also I don't know much about 'Piazza San Marco' so I don't know whether that should be 'the Piazza etc.'
Either way hope I could help :)
