When planning a cruise vacation, many travelers seek moments of peace away from crowds, noise, and high-energy family zones. This is where the adults-only Solarium comes in. Found on many modern cruise ships—most famously on Royal Caribbean International vessels—the Solarium is a tranquil, adults-exclusive retreat designed for relaxation, wellness, and quiet enjoyment.
This in-depth guide explains what the adults-only Solarium is, how it works, who it’s for, what amenities you’ll find, and how to use it wisely. Written with E-E-A-T principles (Experience, Expertise, Authority, and Trustworthiness) in mind, this article draws on official cruise-line information, public health guidance, and hospitality best practices to help you decide whether the Solarium fits your cruise style.
The adults-only Solarium is a restricted-access relaxation area on a cruise ship, typically reserved for guests aged 16 or 18 and older, depending on the cruise line and itinerary. It is usually located near the top decks and enclosed with glass panels or retractable roofs.
