Hi @thupald ,

Try formula like below:

result =
VAR _row1 =
    CALCULATE (
        COUNTROWS ( 'Table' ),
        ALLEXCEPT (
            'Table',
            'Table'[Passenger Name],
            'Table'[CheckIn Date],
            'Table'[Checkout Date]
        )
    )
VAR _row2 =
    IF (
        CALCULATE (
            COUNTROWS ( 'Table' ),
            FILTER (
                ALL ( 'Table' ),
                'Table'[Passenger Name] = MAX ( 'Table'[Passenger Name] )
                    && 'Table'[Name] = MAX ( 'Table'[Name] )
            )
        ) = 0,
        0,
        1
    )
RETURN
    IF ( _row1 = 2 & _row2 = 0, COUNTROWS ( 'Table' ) )

If the problem is still not resolved, please provide detailed error information and let me know immediately. Looking forward to your reply.

Best Regards,
Henry

@thupald try this measure

SUMX ( 
   SUMMARIZE ( Table, Table[CheckInDate], Table[CheckOutDate], "@Cnt", DISTINCTCOUNT ( Table[PassengerName] ) ),
   [@Cnt]
)

Double Bookings = 
SUMX(
    FILTER(
        SUMMARIZE(
            Bookings,
            Bookings[CheckIn Date],
            Bookings[CheckOut Date],
            Bookings[Passenger Name],
            "@Cnt", 
                DISTINCTCOUNT(Bookings[Accomodation Name]) - 1
        ),
        [@Cnt] > 0
    ),
    [@Cnt]
)
