I don't like to think of weight loss as going on a diet because then it feels like losing weight is an option that I can choose to continue with or stop doing. Rather, I prefer to think of weight loss as a lifestyle change where there are no options because I have already made the choice to change what I eat and how much I exercise.
In regards to your weight change, I've gone the other way. Three days ago I was 164, then two days ago I was 165, yesterday I was 163 and today I weighed at 162. Tomorrow I reckon I'll be back at 165! Anyway, to answer your question: yes, fluctuations are normal. I've heard people talking about water-weight affecting the scales, and it also the foods and drink you consumed will affect your weight too. Because my weight changes everyday and can't decide if I'm heavier or lighter, you may find that it is lower tomorrow. If not, don't fret because you can do things to bring it back down
(Last month I was bombarded with weddings and dinners, so I know what you mean!)
Weight loss is 80% what you eat and the rest comes off with frequent exercise. If you want to shed a few pounds before your boot camp, I suggest changing the foods you eat and reading the labels on the foods you buy (I'm forever doing this!), and going for 30 minute walks 3-5 days a week.
