We priced 717 experiences per head for every party size. Below five, per-group tours lose. At five they pull ahead — and keep going. Meanwhile 37.1% of Cancún’s experiences won’t admit a three-year-old at all, which nobody tells you until checkout.

Who’s going?
What fits your 5 incl. an 8-year-old:
The thing nobody tells you
Operators publish the ages they sell to, and plenty start at eight, ten, even eighteen. It is a structured field on every listing, and no booking site shows it to you before you have chosen the day and built the afternoon around it.
Across all 717 experiences we count. Enter your children’s ages once and every card checks itself against them.
Real days out where the booking price does not change because you brought the kids.

The arithmetic
A per-person tour costs about $85 a head whatever the size of your party — that number never moves. A per-group tour costs about $298 for the booking, so its cost per head falls with every person you add.
For two people that is a terrible deal. For five it draws level. For six and beyond, the private option is simply cheaper — and for a family, quieter, at your own pace, and with a guide who is yours. Nobody advertises this because it only becomes true at a party size the industry does not price for.

The same arithmetic, one step earlier. “Sleeps 5” can mean two bedrooms and four real beds, or one room with a sofa bed — and most listings will not tell you which. We researched family stays that publish a capacity and a bed layout in the same cities.
