It was a good deal and we enjoyed Paris. However, there were a number of hidden costs. Air flights were booked with Air Icelandic with no baggage allowance. Each checked bag cost $130 each way. We had 4 checked bags. That added over $1,000. Air Icelandic doesn't include any food, snacks or beverages. They don't even provide ear buds for the entertainment system. Hotel room was included but not city fees which added $240.
We've traveled using Great Value before but were never dinged by the hidden costs. We've done B&B with car to England, Ireland, and Scotland (3 separate trips). No baggage fees, food, snacks and N/A beverages on flights and no extra fees at any hotel or B&B. The hotel (Ibis Styles Meteor-Porte D'Italie) is a 3 star (room cleaning is okay but not great - wire champagne cage under bed but not ours, sometimes towels not changed, etc) but the breakfast buffet was pretty good. The metro station is real close and you can take the 7 line to Chatelet and transfer nearly anywhere. We used RER B from Charles de Gaulle but booked a airport shuttle for departure. The airport shuttle was much more convenient, faster, less stressful, less strenuous and cost about $10 more than RER B to Grade du Nord then subway to the hotel
