Scots are renowned for being adventurous travelers, and also for being respectful with the people and cultures they visit. Backpacking is only one way to visit a country, and it should not be taken as word of Bible.
Backpacking is ideal for summer travels, yet you can undergo a totally different experience in winter, especially when time is of the essence. When Scotland plays Rugby vs. Italy, it generally occurs in Rome, which is generally not suited for backpacking. However forget backpacking and rent a pristine apartment in Rome , through awarded agencies which come handy. While you can still bring your backpacks and leisure outfit, by staying in a comfortable apartment near to all the sights and to the stadium you will be able to experience the best of both worlds.
Nowadays Rome apartments come in all shapes, sizes and prices, competing with other Rome accommodations, but they are more comfortable and safe.
Another advantage is that you can secure your reservations, which is not always possible with hostels, and you also get to interact first hand with locals.
Rugby fans, as everybody knows, are fair and loyal, which makes them well accepted by quality apartment rentals agencies. Actually, by contacting your local hosts to organize your stay, they can become your first local friends, helpful at all stages.
In the end, while you might bring with you your hostel outfit, luggage and backpacks, you will be able to concentrate on the sport event, and have peace of mind about your Rome accommodation.
