My Upcoming Vacation Vent - people need to leave me alone

I'm going on vacation the end of August to OBX aka the Outer Banks in North Carolina. I'm super excited since it'll be my first time going and I can't wait to spend an entire week in a mansion on the beach with some pretty amazing people.

With that being said, I do have some issues with how people have responded to my decision to not take part in all the meals that will be prepared for us. Everyone in the group (around 30 people) will be divided into making either one breakfast or one dinner for everybody. Now that means that it's up to the group preparing the meal to choose what they want to serve to everyone. So basically unless you make a choice not to, you're going to eat the breakfast and dinner that's prepared. Well I've already decided that I plan on making on my own food throughout the week and not to partake of the group meals but of course still eat with everyone. That has seemed to cause some people to question me and my food decision. Some of the vacationers are saying that I've worked so hard so I should enjoy myself that week and just eat whatever I want and just go back to my, now normal, eating habits when I get back. They feel that because it's a vacation I'm being ridiculous with making the choice of wanting to buy my own food when I get there and mostly eating only that. A friend of mine thinks that I should have a little of everything in moderation and just make sure I have a salad with my meals.

I personally feel that EVERYONE needs to mind their own business and let me do what's best for me. One girl was right, I did work hard to get to this point but my reward will not be in the form of food, it will be that new super cute bathing suit or dress or shorts that I was not able to wear before losing this weight. I refused to reward myself by eating whatever I feel for an entire week of vacation, that's just not what I want to do.
***If this something that you like to do, then by all means do what's best for you. I can only state what best for me and my body and the things that I feel comfortable doing.***
Eating whatever I wanted is what got me to 229 pounds, I'm not doing that again. This life that I'm living now is my permanent lifestyle, it's one that I plan to live regardless of where I am or what I'm doing. I like how things are for me right now and I'm sick of having to explain that to others. It's actually quite ironic that they people telling me to eat whatever I want and enjoy myself are either trying to lose a couple of pounds before they get there or lost some weight and gained it back! The bottom line is that I don't walk around telling people to put food down and work out more so I do not appreciate them telling me what to do. My ultimate goal to go on vacation being in the 140's and leaving in the 140's so if that means I don't participate in the 'group' meals then so be it. I want my happiness to be from having fun and feeling comfortable with my body and in my skin and that's something that food just cannot do for me.
