The cost of a bachelor party weekend trip can vary widely depending on a number of factors including destination, accommodations, transportation, activities and food. Here's a rough estimate based on several expense items: 1. lodging: costs can vary greatly depending on the type of lodging you choose and the city you stay in. You could expect around 20-70 euros per night per person, depending on the exact conditions (from tents, hostels to hotel). So, in total, around 100 euros. 2. travel: Again, the costs can vary greatly. If you are traveling within Germany, the cost of gasoline or train tickets could range from 20-100 euros per person. If you are traveling by air, especially internationally, the costs could of course be significantly higher and quickly reach 150-200 euros. So around 100 euros. 3. activities: Again, the costs can vary greatly. You could expect to pay around 70 euros per person, depending on what you do. 4. food: Food and drink could cost you about 50 euros per person per day, depending on your specific plans and where you are - so in total about 100 euros. 5. other expenses: Also think about things like entrance fees, tips, souvenirs and emergency expenses. This could add another 50 euros per person. So overall, you could say that a stag party weekend trip could cost you around 200-500 euros per person, depending on your specific plans and how you travel and stay overnight. A trip to the nature and camping, on the other hand, is much cheaper!
