Great to hear of your plans for a trip to Rome
My family went on a pilgrimage to Rome in 2001.
My main suggestion to you is to go with a Catholic Group.
There are many excellent Catholic tour groups, that are always going over there.
Trust me, Rome is no where to be if you are alone.
If you want to send me a private message, I will look for Catholic Groups for you to go with.
Having a priest as a spiritual guide is sooo important.
Also the group we went with, gets you the cheapest rooms possible. In Rome we stayed in an old convenant. However we went to several places outside Rome, where we stayed in cheap, clean hotels.
If you want you can check out Ave Maria Centre; and Scott Hahn and many good Catholics are always leading spiritual pilgrimages.
I would suggest you take a look into going with a group with a priest.
Good Luck:
(You have lots of time to look into this)
