The concept of the all-inclusive resort is expanding.

All-inclusive resorts where everything is pre-paid—activities, meals and tips, etc.—have existed for decades. But now the concept is expanding to a wider variety of travel options. The guiding idea is transparency: What you see is what you get, and it’s all included. Cruise lines, known for their pricey extras, are starting to include airfare and before- and after-cruise hotel stays in their prices, with Regent Seven Seas and Seabourn leading the charge. The room rate at the new Ovolo Hotel in Melbourne, for example, includes minibar items, WiFi, local calls and breakfast. And packages with Camp Orenda, an Adirondacks retreat, include “headlamps, hydration packs, gators and trekking poles,” as well as fireside meals plus swimming, fishing, hiking and other classes.

These providers are all attempting to create a feeling of “effortless living” (as Ovolo’s website puts it), alleviating that spike of anxiety every time travelers open their wallet and helping them relax. A U.K. survey by predicts a 10 percent increase in all-inclusive travel bookings (from 29 percent of holidaymakers to 39 percent) for 2013 vs. 2012
