Three-generation holidays and big friend reunions need houses that genuinely work at scale: enough bathrooms (aim for one per two bedrooms), a table that seats everyone, and living space so the group isn't stacked on one sofa. Pembrokeshire's large-house stock includes converted farmsteads with multiple buildings, Georgian townhouses in Tenby, and coastal houses sleeping 12–20+.
Book large houses further ahead than anything else — the good ones take bookings a year or more out for summer and New Year. Check the sleeps-number honestly: "sleeps 16" sometimes includes sofa beds and bunk rooms best suited to children.
