Holiday package

No package holidays for sale here, I'm afraid.

This is volunteer helpers who have experience answering specific questions about travel.

Put together a planned trip, post it here and folks will make suggestions.

As Nigel said, this is not a travel agency, so no packages are sold here except Rick's own tours (which are longer than 3 days). But this is easy to plan on your own. First, get a hold of Rick Steves Barcelona https://store.ricksteves.com/shop/p/barcelona-guidebook or Rick Steves Pocket Barcelona https://store.ricksteves.com/shop/p/pocket-barcelona.

Or, if you are younger and more interested in staying in hostels and going to bars and clubs, try his son's new book, Andy Steves’ Europe: City-Hopping on a Budget https://store.ricksteves.com/shop/p/andy-steves-europe-city-hopping-on-a-budget

These books are sold on Amazon as well.

All of these books have an outline of how to spend 3 days in Barcelona. Then, all you have to do is book airfare and accommodation. If you tell us where you live, we can give you pointers on how to get to Barcelona most easily, and the guidebooks have lots of hotel and hostel suggestions, or you can ask here. If asking, be sure to include your requirements (elevator? included breakfast? balcony?) and budget in euros (statements like "affordable" and "pocket friendly" mean different things to different people).

If you want a package oriented to college students (regardless of your age), you can try Andy Steves' Weekend Student Adventures: http://wsaeurope.rezgo.com/details/28017/barcelona?_ga=1.92273434.1436819305.1474385207
