Plan a Multi-Generational Family Holiday

You're trying to book a trip that suits a toddler, two sets of parents and a grandparent with a dodgy hip. Describe the group and the budget, and this plans a multi-generational holiday: the kind of destination and accommodation that handles mixed mobility and mixed interests without anyone being miserable. The trick is everyone getting something, and this sorts it.

<task>
Plan a multi-generational holiday for {GROUP_DESCRIPTION} within {HOLIDAY_BUDGET}. Cover: what type of destination and accommodation works best for mixed mobility and interests (self-catering villa, holiday park, cruise), what activities can be shared versus where splitting the group works better, how to manage different sleep schedules and meal preferences, and the non-negotiable logistics that prevent multi-generational holidays from falling apart.
