vacation next week

I am going away next week, down the shore for 10 days.   I am trying to mentally prepare myself for all the challenges I am going to have to face.   My niece and nephew are going to be there so I know it will be a house filled of yummy goodies.  Like, chips, candy, ice cream.  You name it I am sure they will have it.  
   I am already planning on going for a couple walks a day and maybe rent a bike and take a nice bike ride.    Does anyone have any advice for me on how I can make it through the week being strong and hopefulllly not gaining any weight

Take your own snacks or buy when you get there, like sugar free popsicles or fudgesicles, maybe go online and get some protein cookies and snacks...most of all have fun!!!!... hope that helps.
