There is not fee to check-in to Puerto Rico
if you have your US Customs Decal before you leave the US waters. That decal can be obtained online and is good for one calendar year.
- - T & C is used to be free if you check in and out during "normal" working hours which is virtually impossible you end up paying the "overtime" charges.
- - The D.R. (Luperon/Samana) are highly variable and the supposed average fees
add up to about US$94.
- - I was in BVI last year and the fees for one month was US$22.
