Itinerary/Budget Advice for a New Traveler :)

[mnightingale]

Hi friends!

I am planning a trip throughout Europe on (hopefully) a three thousand dollar (CAN) budget for 3 weeks from May 19 - June 7 of this year. I want to stay in hostels (40 bucks per night or cheaper) and i'm roughly thinking of spending $70/day.

The plan is to go to:

Dublin - London - Lisbon - Barcelona - Florence - Rome

Is this itinerary and 3000 dollar budget realistic? Or am I being too ambitious?

Any help would be greatly appreciated as I am giving myself a headache trying to figure things out.

Thanks
Meagan.
