Hello, we will be in Paris for 5 days. I would like to buy 5-day ticket for zone 1-3 in paris (we are planning to go though main attractions). We would like to go to Versailles. But if we bought the tickets for 1-5 zone, we would loose money because we are not interested in Disneyland and airport lines. So I want to ask what would be the best option for us. Should we buy 1-3 zone tickets and then buy return ticket for RER C line to Versailles ?
