1. The cards come pre-punched with a hole in the corner.
2. Taxis are very prevalent in the Bahamas, just make sure you know what you are paying and getting before you get in the cab.
3. I think the picture package is only for the 8x10's but the pictures they take on the pier might be included (they don't cost as much as the 8x10's though so including them may not be best price wise).
4. There are always partiers and a fair amount of kids, but it's easy enough to avoid both.
5. They do have wheelchair assistance that you can request in the terminal. Right after security they will have employees directing people to the line, ask them for the physical assistance line. (Pro tip, if you want a boarding picture make sure that you let the person steering the wheel chair know, otherwise they might just bypass this step.)
6. The donation is $15 I believe and that gets you the shirt. I received a 3X on Legend because I waited too long to donate.
Congrats to your son!
