Pre-Oslo: How Much?

A quick listing of how much the weekend in Oslo may cost.

• Tickets (Ryanair) ~ 60 zł (15 euro).
• Warsaw-Modlin-Warsaw bus – 40 zł (10 euro).
• Rygge airport – Oslo – Rygge airport – 300 NOK (35 euro / ~ 150 zł). Rounding up NOK to 0,50 zł for easier counting.
• Hostel/dormitory for 2 nights (just bed and breakfast) – 560 nok (66 euro / 280 zł).
• 24-hours ticket (zone 1) – 90 nok (11 euro / 45 zł).

Let’s say it’s 600 zł (150 euro) without food. (I’m scared about food prices). I already visited museums so I can get just transport ticket, instead of 320 NOK Oslo pass for museums and transport.
