Is ALL Accor Platinum worth it for families

I recently got Platinum and travel as a family of 2 adults + 2 kids. For me, the biggest value is free breakfast, lounge access and possible suite upgrades.

With four people travelling for 7–10 days, those benefits can save a lot of money.

For families with Platinum, has it been worth it for you? How has your experience been with breakfast, lounge access and upgrades?
