1. Past simple tense: The answer consistently uses the past simple tense ("didn’t have," "were," "stayed," "did go," "enjoyed") to talk about childhood experiences, which is appropriate for describing past events.
2. Contrast and concession: The use of "although" introduces a contrasting idea, showing the ability to connect ideas smoothly. The phrase "I do wish we had traveled more" uses the past perfect to express a regret about the past, which is a more advanced grammatical structure.
