I would suggest flights by Level, Norwegian and Vueling. Don't book Primera and Ryanair!
* Baggage fees are not applied. We only brought one luggage for both of us. Meals are not included :( But! It's only $395 for 3 flights. Can't beat it. Bring your own wine and sandwiches on the plane! Also, don't buy seats. Just arrive early to the airport and request seats together
2. Book Hotels:
In PARIS: Nov'27th-Nov'30th
Close to Eiffel Tower: ($416 for 3 nights total) Can find cheaper
3. HOTELS IN ROME: (Nov'29th-Dec'3rd) From $151 for 3 nights.
