Aruba, being in the southern carribean, has very relialble beach weather in late March and April. It is a great sunny vacation to jumpstart spring after a snowy winter in the Northeast.
That turquoise water and lovely beach means a relaxing week with a couple of good books and nice raft floating.
In the Palm Beach area you can enjoy a nice stroll to a wide choice of happy hours and restaurants. No need for a car or all inclusive plans. And we enjoy the people and watercraft watching more than the less busy but still pretty Arashi Beach.
The only troublesome thing is the unleashed dogs in the neighborhoods with home rentals, and ability to get a palapa if not at a Palm Beach hotel. Umbrella rentals are there for $25/day at Moomba Beach Bar.
