I know exactly what you mean, with this spreadsheet. Therefore I made a "Trip Management" template in Excel (see tab for your language, I made it in NL, DE and EN), which I use for most of my trips.
You can fill in:
start date and number of nights
as a bonus fill in expectes gaz price and consumption and it calculates budget
start/finish place
hotel
link to the bookingsite
mark the checkmark when made a reservation
on trip, insert the real gazpayment and you see how it matches your budget
Save it with the name of the trip and an new excelsheet is made.
You can find it here: Trip Management Lite.xltx
