A family wet-weather day without the convoy chaos.
Spend energy first
Book Hangar 5, swimming or climbing before everyone else reacts to the forecast.
Choose food near the activity
Avoid driving back to Trefin between every part of the plan.
Lower the intensity
Add bugs, a film or the cinema room rather than forcing a second major attraction.
Before you promise the plan
Five checks save sixteen opinions later.
“If your group spans toddlers to teenagers, tell Daisy the ages. She can help you avoid a plan that sounds family-friendly but only suits half the children.” — Daisy
