We're going to Bonaire in May and staying at the Divi. This will be our fourth trip to Bonaire and first at Divi. Since I was last in Bonaire in August '06, the booking agent tells me that I will not need to repurchase the $25 marine park tag or complete another "orientation" prior to dving, as the tags are good for 12 months. My impression in the past has been that the tags go by calendar year and that you'd need a new one for 2007 no matter when you were there in '06. Does anybody know the answer to this? I still have the tags from last year and I even have the paperwork receipts, although these are undated, which makes me even more skeptical that they can be re-used.
