Ladies: For poolside, take bikinis and a coverup to reach the pool from your cabin. Don't forget a beach bag to hold your stuff if you decide to tan all over around the pool. For day time fun, bring casual wear or tropical fashions, depending upon the itinerary. Of course hats, ball caps, shorts, tops, sundresses, sandals, jeans, athletic and dress shoes will prepare you for most action and daytime activities. For theme nights, bring your costumes. If you choose to be casual and minimize packing, don't worry about the extra theme stuff but include dresses or slacks/blouses for evening dining and parties. Dress for the themes...or not. It's your cruise and your vacation to do as you please.
Gents: Pack casual and semi-formal attire. Bring shorts, jeans, ball caps or hats, sandals, athletic shoes or trainers, street shoes, dress slacks and collared shirts. Muscle shirts, polo and theme T-shirts are always fun. If the cruise includes a formal night, don't worry. A Tux or suit is NOT required but it is fun to dress to impress if you so choose. For dining in the evening, guys, leave your jeans in the room and enjoy dressing up a bit if you care to.
For Ports of Call and optional excursions, take walking or athletic shoes plus aqua shoes or flip flops for beach or pool wear.
Take toiletries including sunscreen, deodorant, body wash, lotions, shampoo, lady's items for good hygiene, etc. Note: Your cruise cabin and bath typically include soap, body wash and shampoo plus a hairdryer and makeup mirror. Don't forget your dependable insurance: Ziplock bags in case your liquids might leak or spill along the way.
Personal items: Camera, iPhone, charging cords for your phone, camera, toys, other electronic devices such as your computer or tablet. Internet service and WiFi are available for an extra fee. You can pre-purchase the service online prior to travel. TIP: Power outlets are limited. Most cabins include both 110v and 220v electrical service. To use the 220v, bring your adapter/converter to supplement your power needs. AND, bring USB cords to re-charge equipment that's compatible with USB charging.
Beach or Pool Towels: Don't pack them unless you have to have one. The ship provides pool and beach towels so don't pack anything extra unless you want to.
TIP: Pack a carry-on or bag with wheels for your first day's clothing once you board the ship. The bag is also handy to carry your passport, I.D. and other documents with you as you travel and board this ship. Your bags will be delivered to your cabin later in the afternoon -OR- into the evening. Pack you swimsuits or casual clothes to change into once you're in your cabin. Most cruises lines allow cabin access after 1 PM, but may vary. Your carry on is also handy on the last night and when departing the ship. Your large luggage will picked up outside your cabin by about 10 PM the night before you dock the next day.
