If you haven't made the novena - you can start and finish one today - the day before the feast of Our Lady of Guadalupe. Offer your prayer today, and ask Our Lady to accept it as if you had prayed and fasted all nine days.
If you can't make a pilgrimage to Guadalupe, you can visit your parish church in honor of Our Lady and ask her to accept your visit as if you had walked barefoot to her shrine in Mexico City.
If you can't do that, you can sit quietly in your room, prayerfully unite yourself to all of those who have made the pilgrimage, as well as the whole Church, who honors Our Lady on her feast, and be confident that your desire to honor Our Lady is pleasing to her and gives glory to the Blessed Trinity.
The laborer, the poor, the lame, the shut-in cannot always make costly pilgrimages, but they can do so spiritually, in their hearts. It can be as efficacious as making a Spiritual Communion. Some of the saints did such things with so much fervor, some were given the grace of bilocation.
You don't have to do any of that however, and you surely do not have to take my word for it.
