Have a great time! I will add my 2 cents of be careful. Stay in very public places and don't go into any isolated places on your ride. Most guys online are just normal joe blows but it only takes one.
I can relate to the whoo hoo giddiness - feels like you are 16 again
I have been corresponding with an epal I met online about 5 years ago, we feel like we know each other well even though we have only seen each other face to face for 1 hour a year ago. He lives in Utah and I am in NoDak. (he used to live here and a lot of my friends knew him well so I have come to find out)
My sister met her DH of 6 years online. She was bombarded by the usual "be careful" "don't do this or that" (mainly by me). But he turned out to be a great ordinary guy from a very normal (whatever that is) family
Have a super time, just keep your wits about you and remember to not give out too much information.
It's about the journey and being in the moment, not about the destination
