Hello, this is our fifth Olivia trip. We are hooked. there is nothing like "Lesbian Land" or should I say floating city for a week!
Bring...all the first aid you can think of. Any medical needs supplied on/from the ship are outragelessly expensive. Band-aids, insect repellent, after-sun lotion, LOTS of sunscreen, anti-diarreha, constipation, sinus, pain reliever like Advil, heartburn medication, Benadryl and any other medication you can think of. They really don't take up that much space as compared to the overpacking of clothes you are probably going to bring.
We also bring duct tape...just in case the luggage breaks or in one case, my wife's strapless bra hooks broke, so we used the tape. It truly is a fix all. We also bring a small flashlight, travel alarm clock, small backpack for shopping at port. We bring a small amount of thin rope or sting and some clothes pins in case we want to do a little laundry. There is a small clothesline in the shower, but the extra has come in handy.
If you want to wear a tux on formal night, but don't want the hassle of packing one, you can rent one from Holland America. Just order it on their website and they will have it waiting for you in your room when you arrive. After you are done with it, your cabin steward will pick it up the day before we get home. They also have evening gown you can rent, but they are very generic, so if your a fem you probably want to bring your own.
As for everyday wear, bring what you are most comfortable in. We usually buy a lot of t-shirts in port so we don't bring too many and we still end up coming home with more shirts than we went with.
Anyway, I'm babbling now. Just know that you are about to experience something that can't be put into words. The OLIVIA experience! Just be ready to have fun and enjoy "lesbian land" or should I say floating city for a week. It is the best.
