Access, fees and practical arrival tips
Hotel guests can use the on-site fitness center and pool during the season; the resort charges a mandatory nightly resort fee that (per published listings) includes fitness-center access, in-room bottled water, in-room coffee and internet access. The dossier does not list a separate mandatory pool fee for registered guests.
The property may require a refundable incidental deposit at check-in; published sources list a daily refundable deposit amount. For any special requests (early check-in, pool cabana reservations) call the hotel ahead of arrival.
- Mandatory resort fee is published on booking pages (includes fitness-center access and internet; check your booking for details)
- A refundable deposit is commonly collected at check-in (published listings cite a typical amount)
- If you need cabanas, early arrival or poolside service, contact the resort or the BookResorts agents (24/7) at +1 (888) 605-1350

Practical packing and etiquette reminders
Bring basic pool items: a swimsuit, sunscreen, sunglasses and a hat. The dossier does not specify towel policies; most hotels provide pool towels, but confirm with the front desk if you plan to rely on hotel towels all day.
Follow posted pool rules while on deck and respect cabana reservations and food/beverage service. If you plan to visit the spa or dine before/after pool time, check dress codes for specific restaurants (for example, Voltaggio Brothers Steak House lists a smart-casual dress code).
- Pack sunscreen and a cover-up for moving around the resort
- Confirm hotel towel policy at check-in if you’ll be using the pool all day
- Check restaurant dress codes for evening plans (Voltaggio Brothers Steak House: smart casual)
| Item | Why it helps |
|---|---|
| Sunscreen | Summer sun and waterfront reflection increase exposure |
| Cover-up | Useful for moving between pool, restaurants and public areas |
| Phone/charger | For cabana F&B orders and to contact concierge if needed |
