From $480/night for 2BR — expensive but full kitchen saves significantly on dining. Pricing Value scores 64/100 — fair for what you get.
No dedicated kids' club listed, but there's on-property play (pools, playground, or game room) and Kid Amenities scores 84/100. Plan to be hands-on; don't count on supervised programming.
Pricing Value at 64/100 is the real soft spot — you're paying a premium versus comparable peers; check whether the amenities you'll actually use justify it.
