Suzy is absolutely right about the need to shore dive while here in Curacao!!
There are some amazing shore diving here that must be done (Examples include Porto Marie, Casa Abou, Pierbaai, Alice in Wonderland, Sweet Alice, Shipwreck Point, Playa Jeremi, etc...) However in saying that, there is some amazing diving sites that just cannot be done by shore if you want the full effect of Curacao. (Examples in Watamula, Rediho, Paradise, Kortape, Hell's Corner, & Mushroom Forest just to name a few!!)
The bottom line is that to experience Curacao, you should consider a combination and not limit yourself to one or the other.
Experience all of Curacao!!
