Here's a few tips from Jamboree veterans to help you prepare for a fabulous Jamboree.
Get Yourself Organised
Don't leave your packing until the last minute.
Bring dirty clothes bags so you can keep your dirty & wet (& smelly) clothes out of the way.
Your Contingent or Line Leader has probably given you a packing list - use it!
Read this handbook!
Be Prepared
Practice washing up. Your health & hygiene depends on the quality of your washup, and your free time depends on the efficiency of your washup!
Practice hand washing your dirty clothes.
Bring enough medication to last the duration.
Read emails & bulletins from your PL, Leaders & Contingent.
Bring some badges to swap with the people you meet.
Get lots of camping practice.
As BP said: Be Prepared. Be prepared for what? Why, for any old thing.
Look After Yourself & Your Mates
Your Jamboree campsite is home for nearly two weeks. So it's really important to set up a top quality campsite right from the start!
Be sun smart. Getting sunburnt hurts!
Stay hydrated - it's hard to have a great time with a headache!
Remember that others may get cranky when they're tired or things aren't going well - be supportive & give them space. (And check, maybe it's you that's tired and irritable?).
A great Jamboree experience involves Fun and Work - so pull your weight and share the load.
Get organised early each day - know what you need & where to be, so you're in the right place, with the right gear, at the right time.
As BP said; The most worth-while thing is to try to put happiness into the lives of others.
Challenge Yourself
Give everything a go!
Teamwork makes the Dream Work.
Be respectful of others, particularly as you develop your new patrol and new Unit.
Be flexible - not everything will go your way, or to plan.
Be ready to make new Friends for Life!
As BP said: A Scout smiles and whistles under all circumstances.
