Regent Seven Seas is the most all inclusive cruise line in the world and here’s what that actually means. If you’ve only sailed mass market or premium cruise lines, Regent is going to feel like a completely different universe. Every suite includes unlimited shore excursions in every port, roundtrip business class flights on intercontinental sailings, premium spirits and fine wines, specialty dining, pre-paid gratuities, unlimited WiFi, valet laundry, transfers, and even a pre-cruise hotel night
