Preheat oven to 425 degrees. Line a rimmed baking pan with a sheet of parchment paper. In a medium bowl, toss the green beans, garlic and olive oil together until completely coated. Then, spread the coated green beans on the lined pan in a single layer without crowding. Season with salt and pepper, then roast in the pre-heated oven for 15 minutes. Remove from oven once during this time to turn the beans so they cook evenly. When finished roasting, remove from oven and place beans on serving tray. Before serving, drizzle with extra virgin olive oil and sprinkle with grated Parmesan cheese. This makes a great recipe for Thanksgiving dinner sides.
Hotel prices definitely go up in around Christmas so it's best to come early in the month if that's possible, but it's still a pretty good bargain even during the peak weeks. Book early if you can because the better and cheaper hotels will fill up first, of course. Also consider a side trip to the Mendoza wine region, Patagonia, or the amazing water falls of Iguazu.
Tamarindo and Smara are two of the most popular beach areas, but there are other good choices in the area as well. This part of Costa Rica is known for large chain resorts on the beach, and the 4-star resorts can be pricey, while the more traditional 3-star hotels are still very reasonable. Costa Rica is obviously one of the hot countries in December in both temperature and popularity, so book early.
