Thank you to everyone for all the fantastic advice and help.
As it is, my retirement has not gone as well as expected, and so we are trying to do as much with the money we have as we can.
That said, previously, we would love to just get everything on the caye and in country but as it is, we'd also like to do more than eat and drink and stuff like diving, cave tubing, lining, and boating up the river to the ruins isn't cheap.
So, considering that taking this vacation will cost me my current job(after a year they are refusing to honor my paid vacation since I am a commission only manager)and my retirement doesn't kick in until I get to 59.5 years old, I need to make due while not passing my money stress onto my kids... who I hope still think of me as the breadwinner I used to be before I retired.
So, that's why I am looking to bring stuff like packaged foods and some booze with me so I can afford to buy more and experience more while I am on AC.
We are also in the process of getting our dive stuff fixed since we haven't used it in awhile.
Thanks again for all your help!!!
