| Challenge: | Existing benchmarks such as TravelPlanner and TravelPlann+ rely on semi-synthetic data and lack key real-world constraints. |
| Approach: | They propose a spatio-temporally coherent travel planning dataset incorporating real-world constraints, including public transit schedules, public events, varied attraction categories, and user personas for enhanced personalization. |
| Outcome: | The proposed dataset significantly improves meal scheduling, improving performance from 61% to 80% in the 7-day scenario. |

| Challenge: | Large language models exhibit the ability to generalize given few-shot examples in their input prompt, an emergent capability known as in-context learning. |
| Approach: | They investigate whether large language models use in-context learning to generalize given few-shot examples in their input prompt. |
| Outcome: | The proposed model can generalize given few-shot examples in their input prompt, an emergent capability known as in-context learning. |
