awhhhhh Medi. You are one lucky lady.
Now I stopped here as a fellow anxiety sufferer to tell you to QUIT TRIPPING. You have nothing to worry about my friend. Count your blessings. You will LOVE the GP. It is so pretty and colorful and right on the water. You will be in heaven. The tipping situation is what it is - although I don't believe in it, the policy was put in place so people like yourself don't have to worry about tipping every time you get a service on your vacation. Enjoy it what it is for. If you want to tip someone do it outside of the gate so no one will get in trouble.
You are a generous and kind woman but you must remember that you too are living on a budget- you should worry about what you can do to make yourself strong and healthy while on your trip and not be worrying about what you can do for others. I recently heard Suzi Orman say something I have been repeating a lot lately - "If you are in dept you CANT help others - the first thing you need to do is pay down your debt"
I'm so excited for you Medi - it sounds like a dream vacation.
