Long and Curly, or Tucked and Pinned?

Now that I have a dress, it is time to figure out how I am going to do my hair for the Europe bridal shoot(s). My hair is very long (halfway down my back), something I have been waiting to say for a long time now, and so I actually have quite a few possibilities. It doesn't hold curl well, but that is mostly due to the fact that I hate using hairspray. I am thinking half-up is going to be the best option. I have spent a lot of time browsing through the fantastic photobucket hair/makeup inspiration album by be_byte6. Here are a few inspirational photos I have collected so far.

I am not sure what the humidity of Italy is like, but their is a chance that this will just fall flat as soon as we get outside. I also can't decide if I like the hairstyle or the model who is showing it off. Isn't she gorgeous?

Kind of the standard, curly pulled back half-up hairstyle. Might actually cost us more than it's worth since it kind of needs some type of accesory pinned in with it.

This actually might be my favorite. Not sure I would be able to hide, or blend in those messy ends as well as that stylist did. And I don't have a pretty comb to stick inside.

Definitely the safest option, as this is a hairstyle I do for myself quite regularly.

Anyone have any ideas? Anything particularly European or fashion forward that a little country girl like myself can accomplish in our tiny hotel room in Rome, with just a straightener and medium barreled curling iron?
