Yes, basic brewed coffee is free and available 24/7 on Oasis of the Seas in 2026. You can find complimentary regular and decaf coffee at the Windjammer Marketplace, the Main Dining Room, and Café Promenade on the Royal Promenade. However, there is a clear distinction between "free" coffee and "specialty" coffee. If you want a latte, cappuccino, or any espresso-based drink from the Starbucks kiosk or the Vitality Café, you will be charged an additional fee (typically $4–$7) unless you have a premium beverage package. Additionally, the coffee served via room service is free for continental breakfast, but most other room service orders now incur a $7.95 delivery fee. For most cruisers, the free coffee provided at the self-serve stations is more than adequate for a morning "pick-me-up" without needing to spend extra.
