Location and atmosphere. A rooftop pool sits on the top floor or upper deck of the hotel, so you get skyline, water, or mountain views instead of a courtyard or garden. Rooftop decks tend to be smaller and more social, often with a bar on the deck, music, and a crowd that stays into the evening.

Some are. Rooftop decks with a bar or DJ often limit access to adults, sometimes 18+ and sometimes 21+, while others welcome kids during daytime hours. Age rules are set by each hotel and listed on the property page, so check before you book if you're bringing anyone under 21.

Rooftop decks are more exposed than ground-level pools, so hotels may close them for lightning, high winds, or storms. If the deck closes during your visit, contact ResortPass support. Before you book, check the hotel's cancellation policy on the listing so you know your options if the forecast changes.

Weekday mornings and early afternoons are the quietest, with the best odds of finding an open lounger. Late afternoon into sunset is the most popular window, especially on weekends, when rooftop bars fill up and some hotels add a DJ. Rooftops can also get hot, particularly midday, so a cabana or daybed is worth it in peak sun.

On a busy day, it helps. Rooftop decks usually have less space than ground-level pools, so the limited loungers go fast on weekends and holidays. A cabana or daybed reserves your spot and adds shade, and some include perks like food and drink credit, towels, or dedicated service. What's included varies by hotel and is listed in each pool pass description.

It depends on the hotel. Some rooftops are laid-back pool decks, while others have more of a party scene with a DJ, bottle service, and a more dressed-up crowd. Swimwear is expected on the deck itself, but many hotels ask you to wear a cover-up and shoes at the bar or when walking through the lobby. At most locations, outside food and drinks are prohibited, but check your property listing details for specific policies.
