I am planning a trip to South Padre just after Christmas. Anyone been there during that time? Also, would like to know which is the best airport to fly to - Harlingen or Brownsville? I would like to have time to climb the lighthouse at Port Isabel. Is it within driving distance if staying on the beach? I've seen kudos for staying in condos instead of hotel rooms; are there small ones for just one or two or are there some bed and breakfasts available in the area? on the beach?
