Believe me, you are in good hands and this will be one of your best investments to enjoy your trip to the fullest anywhere in the world.
No matter the destination, I will give you tips according to it when it comes to:
1. What to take with you. So you do not miss anything back home. First-aid, toiletries, etc.
2. What to be aware of. Every place is different and it it always better to know what to expect.
3. Which vaccines are necessary. Health is a priority! every country/region has different requirements and recommendations.
4. What to pack. Depending on when and where you travel. Pick the right clothing and the right amount to travel comfortably.
5. What to do. Outstanding experiences and activities await you! from tracking gorillas to learning meditation with a lama. You name it.
6. Anything you need or require.
Beyond a travel agent. I travel constantly. I do this every day. I recommend from experience.
