All-inclusive nostalgia is having a moment, and Sandals — the couples-only Caribbean brand those unforgettable '90s infomercials made famous — is currently dangling some of its biggest discounts of the year. There are 17 Sandals resorts spread across the region, from Jamaica and Antigua to St. Lucia, Barbados, Curaçao, the Bahamas and beyond, and several of them have genuinely substantial offers attached until early November.

The headline deal is the Great Jamaica Comeback Sale, running until November 2. Book three nights or more and you can save up to $1,500, plus up to $500 in air credit on stays of five nights or longer. The maths scales with your trip: five nights at Sandals Jamaica South Coast gets you $630 in instant credit plus $350 in air credit, while a 10-night stay at Sandals Jamaica Caribbean Cay unlocks the full $1,500 plus $500 toward flights. Travel must be completed by December 31, 2028, so there's plenty of flexibility to plan ahead. Book a five-night Jamaica trip right now and Sandals throws in a free excursion — think climbing Dunn's River Falls or drifting down the Martha Brae River on a bamboo raft.

Not heading to Jamaica? A few other routes to savings are worth knowing. Active and retired US and Canadian military members, plus police officers, firefighters, EMTs and active FEMA staff, get 10% off room rates after verifying through SheerID — and it can often be combined with other offers. Return guests should look at Sandals Select Rewards, the loyalty programme that earns points redeemable for vouchers and discounts, with top-tier members getting perks like complimentary massages and private airport transfers.

Travelling with friends has its own payoff. The 'Share the Love' referral programme hands you up to 50,000 rewards points a year — worth $1,250 — if you refer up to five people to a Sandals or Beaches holiday, and each friend starts their first booking with 10,000 points ($250) of their own. Families should note that Sandals is adults-only; the brand's sister line, Beaches, covers the kid-friendly side with waterparks, kids' camps and Sesame Street characters.

Flexible travellers have the best hand of all. Sandals' Last Minute Deals section offers a free night at select resorts booked 30 to 60 days out — currently applying to places like Sandals Royal Barbados and Sandals Saint Vincent. The savviest move is stacking: combining a last-minute free night with an active sale or the service-personnel discount.

If a code refuses to work, check for typos and expiry dates, confirm your stay length meets any minimum-night requirement, or try a different browser before contacting support.

For honeymooners, anniversary trips or anyone who wants flights, food, drinks and diving bundled into one price, these stacked offers can shave four figures off a Caribbean week. Just remember the Jamaica sale window closes November 2.
