Family-Friendly, High-End All-Inclusive Travel: Seeking Expert Advice

Overview:
I’m helping my family plan an all-inclusive, high-end getaway that accommodates a multi-generational group. My goal is to find an excellent experience without booking a large number of separate rooms, while keeping food quality high and the beach options appealing. Spring break is the target window in the third week of March.

Group and room needs:
– Total guests: 10
– Ages: 13, 12, 12, 9, 6, plus four adults
– Bedroom configuration: ideally two rooms total
– Room 1: could be 3 adults and 3 children
– Room 2: could be 2 adults and 2 children
– Bedding requirements: all beds must be Queen or King size

Destination and beach criteria:
– Beautiful beach with no sargassum concerns
– Beach access that is clean and relaxing
– Preference for a location less expensive than Beaches Turks & Caicos, but willing to invest for a premium experience

Amenities and experiences:
– All-inclusive package with top-tier dining (very good to great food)
– Family-friendly atmosphere, but with a higher-end, refined vibe
– Activities and entertainment suitable for a wide age range within the group

Timeline and challenge:
– The booking window feels tight for a March spring-break timeframe
– The logistics of coordinating accommodations and activities for 10 people are proving overwhelming

What I’m hoping for:
– Destination and resort recommendations that fit the above criteria
– Guidance on how to negotiate room configurations to minimize the number of rooms
– Tips for ensuring excellent dining experiences and beach conditions
– Advice on securing availability during a peak travel period

If you have any suggestions, experiences, or specific properties that match these requirements, I’d greatly appreciate your insights. This is my first time organizing a trip like this, and I’m grateful for any help!
