Thank you. I just wanted to know if everything is OK.

Question

Which sentence should I include (4 or 5)?

1) At the end of the lessons we walked in (??) Dublin and also visited some museums.
2) On weekends we made excursions.
3) On a Saturday we went to Kilkenny, a medieval city and saw its sights. I also played rugby.
4) I like all of this holiday except the food because the Irish use a lot of butter and they don't eat bread or pizza.
5) I really had a good time on holiday. The only thing I didn't like about my holiday was the food because Irish people use too much butter and don't eat pizza or pasta as we do.

Answer 1

Commas needed in 1, 2, and 3.

Use 5 rather than 4.
