If you fly out of Goldson, Yes it is BZE it only costs $11 US more. I would save the time and just go from there.
If you are a Group of people, it may be a savings but more time consuming. It depends on you, personally.
We fly right from Goldson.
Yes, your taxi will cost you $20 US to go to Municipal. It doesn't make sense unless there is a group. My personal opinion
Go, enjoy and have fun for me too
