1. One realistic morning and one realistic afternoon activity per day, no more, with travel time between them
2. At least one child-friendly meal stop per day, named by area rather than a specific restaurant
3. A rainy-day indoor backup for at least one full day
4. A note on which day is the busiest and which is the recovery day
