ContainsValue is like a foreach loop.
ContainsKey is faster :
This method approaches an O(1) operation.
As for ContainsValue, I can't tell for sure, but I think there won't be much difference to a loop .
ContainsKey is nearly O(1).

Maybe you have to define a class say class Pair to hold your two value, and use int as the key, KeyValuePair<ulong, ulong>>();
If you want to add in a value: Key=1, Pair = {2,3}

You can try.
The value in advance:
DECLARE @var int SET @var = (SELECT count(*) FROM myTable WHERE @checkout > checkin AND IDcolumn = @IDcolumn)
@var would then be equal to 1 if the value passed.
