If everything you own disappears though, the main things you need to survive this trip (which should therefore be on your person/in your carry-on luggage and never let out of your sight) are:
Decorated boots/bag (and any other special orders!)
Fete and ferry tickets sent to you from Trinidad (if not waiting on you when you get there)
Extra contacts and cases
Everything else can be purchased/sorted out but these are a must, especially the first two!
...And did you tell your bank your dates and destination of travel so they don't freeze your card for fraud protection if you decide to or need to use it?
