I would bring it and get one of those attachments that let you roll the car seat around like a stroller. There'll be two of you so one can handle LO while the other handles the car seat?

I would definitely take & use your own. You just can't know the history of a rented seat, if you have all the necessary pieces to install correctly, manual, that it for sure won't be expired, or that there won't be a mistake and for some reason you not get a seat.

I'd also take my seat to the gate & see if by chance it can be accommodated on the plane (you can even call the morning of your flight to see if they flight is full).

Bring and gate check the car seat alone with the stroller. I just flew (alone) with LO, and it wasn't a pain to bring it. In fact, since the flights weren't full, I was able to bring it on the plane (even though LO was a lap baby). It was so nice to be able to sit him down while I ate or went through my bag, etc. additionally, it's just nice to have your own car seat to use in the car since you're already familiar with it.

Also, since you have a short connection, you can ask them to unload the stroller (and car seat if you can't bring it on the plane) in the Carribbean. No need to grab it in between flights if you're going right to the gate. That's what I did, anyway!

Do you have a snap and go or a friend who will let you borrow theirs? We went to the Caribbean in September, and borrowed a snap and go - that way we could use the car seat as part of the stroller in the airport rather than having to lug it around in addition to an umbrella stroller.

FWIW, not sure which island you are going to, but you will definitely want a car seat. Most C islands are *really* steep and hilly and the drivers are maniacs - I would have felt very uncomfortable without a good car seat.

I would take yours with you. You can check a stroller or car seat for free if you're traveling with an infant. We bought an awesome Brica car seat bag (it can be worn as a backpack and is really nice and sturdy). The best part is it has a huge zipper in the front that we put a bunch of clothes in. So we got to check that stuff for free, too That way you also wouldn't have to worry about lugging it through the airport or between gates.

@JoJoGirl: We got it at BRU. The one we got fits convertible seats as well, so it is pretty big. But it doesn't look as big with just the infant seat in it. We figured we might as well get one that fits convertible seats, too, so that we can use it for a long time.
