May Honeymoon – Beach and Countryside?!

Hi There! Looking for some help while getting into the thick of honeymoon planning. We are planning to go the last two weeks of May. Hoping for 12-14 days with a budget of about $12,000 (not including flights, we have lots of airline points we will use). I have two very different thoughts right now.

1) Europe Beach for 1/2 and Europe Country Side for 1/2 – Happy to fly in between the spots.

• I love a beach and my fiancé gets bored very quickly so European beach town is a great in between. It would be so great to be able to walk to the beach but also into a town for meals. We love food, wine, live music, little bars, etc. Hoping to send about 6 days and happy to switch locations once here (maybe part of the town in a town and part on an island?)
• Looking for the second half to be in a very relaxed place where we can bike, hang out, maybe wine tour, eat all the food. Beach is not a requirement here but even a river or lake near by would be a plus. Same thing, hoping to spend 5/6 days.

2) South America – Argentina

• Doing lots of research and Argentina has been very intriguing to me. I think it kind of accomplishes a relaxing but adventurous honeymoon which is what I think we are going for.
• Thoughts: Fly into Buenos Aires, hit Mendoza for some wine tasting, and one last stop closer to Patagonia. My fiancé loves to fly fish and I like to hike so could be a cool mix of everything.

I would love to hear any suggestions or places that may accomplish both a relaxing but still adventurous location!
