If you use dates as if they were amounts, then this problem is described with solutions here:
http://www.mcgimpsey.com/excel/variablerate.html
Subtract the price for the start date from the price on the end date.
In your case, for Hotel A, I got 3480: 30 days at 50, 7 at 90 and 9 at 150
The formulas gave me 3730 - 250, again 3480.
Instead of the formulas shown in the link above, you can also use a UDF; text at the end of the message.
If you're new to UDF's there is also an instruction on how to use them.

Function PercPerSegment(Amount As Double, Table As Range) As Double

' Progressive pricing
' First argument is the quantity to be priced
' or the amount to be taxed
' Second argument is the Price or Tax% table (vertical)
' Make sure both ends of the table are correct;
' usually you start with zero and the corresponding price or %
' Any value should be found within the limits of the table, so
' if the top slice is infinite, then use
' something like 99999999999999999 as threshold
' and =NA() as corresponding value
Dim StillLeft As Double
Dim AmountThisSlice As Double
Dim SumSoFar As Double
Dim Counter As Long
StillLeft = Amount
For Counter = 1 To Table.Rows.Count - 1
AmountThisSlice = Application.Min(StillLeft, Table(Counter + 1, 1) _
- Table(Counter, 1))
SumSoFar = SumSoFar + AmountThisSlice * Table(Counter, 2)
StillLeft = StillLeft - AmountThisSlice
Next
PercPerSegment = SumSoFar
End Function

Pasting a User Defined Function (UDF)
Niek Otten, March 31, 2006
If you find a VBA function on the Internet or somebody mails you one, and you don't know how to implement it, follow these
steps:
Select all the text of the function.
CTRL+C (that is, press and hold down the CTRL key, press C, release both). This a shortcut for Copy.
Go to Excel. Press ALT+F11 (same method: press and hold the ALT key, press the F11 key and release both). You are now in the
Visual Basic Editor (VBE).
From the menu bar, choose Insert>Module. There should now be a blank module sheet in front of you. Click in it and then
press CTRL+V (same method.).
This a shortcut for Paste. You should now see the text of the function in the Module.
Press ALT+F11 again to return to your Excel worksheet.
You should now be able to use the function as if it were a built-in function of Excel, like =SUM(..)
