mshieny, I say all you need is tennis shoes. I can't imagine hiking to the top of Belvedere, we rode a scooter and it took quite a while to get to the top!

You shouldn't get motion sickness in the jeeps, I can't sit in the back seat of a car either and I was fine.

I can't remember if you needed adapters for the outlets :(

I would bring a pair of comfy shorts to lounge in the evening. Especially if you have a balcony and plan on sitting on it at night!

I always carry one of those tiny fold-up umbrellas in my excursion bag.
