I tell people that taking a vacation in Aruba is like the movie "Groundhog Day". I tell them this because on their first day of vacation they will wake up to beautiful sunshine, followed by a glorious day on the island, followed by a spectacular sunset, followed by a delicious dinner, followed by many fun activities for the evening. When they wake up on the second day (and every day after) - they will have the same amazing experience. An Aruba vacation is a guarantee of sunshine and relaxation and delivers that same repeatable experience again and again and again.
On the other hand, there is a side of me that agrees with Ladder 4 and doesn't want to tell anyone about this amazing island! ;-)
