Little bit of strange that self-catering (no meal) is more expensive then full board - FB

image

or I missed something?

Also I see reservation with Check-out status
without any guests (0 adults, 0 children, 0 babies)

Sample view:

127 records / reservations (38 with 0 nights, others with stay nights different from 0 ).

ATTENTION ALL PARTICIPANTS

The PBI File contained in the Modelled Dataset zip file contained an error. This has been fixed and it is fully functional now.

Please see PBI File here below for your use, please update your files.

Sorry for the error, please if in doubt do not hesitate to contact me or post in this forum.

Hi Federico,
Thanks for setting out challenge 22.
Just wondering how the lead time is worked out?
Thanks,
Anupama.

@Abee,

This is the proffesional definition “the number of days between the time a guest books their room and the time they are scheduled to arrive at the hotel”. Nonetheless, I have notice some discrepancies so please be aware.

I hope this helps.

Thanks Federico - I thought it was and was trying to get the days in between to add up to confirm it to myself. Thanks for letting me know about the discrepancies.
Anupama.

Hi @Abee, @FPastor
I think that the Lead Time should be taken regardless of the Reservation Status Date since of the 141,585 total rows, only for 5089 the Lead Time coincides with the difference in days between the Arrival Date and the Reservation Status Date.

Can it be that the date of the reservation status changes when the reservation status changes and they are not giving us the data of the reservation date, which would have to be calculated by subtracting the arrival date minus the waiting days ?

Agree with Jose, discrepancies are obvious.

Thanks

Hi,

Not sure what to make of the is_cancelled vs. reservation_status fields.

image

For is_cancelled = 0 all rows have the “Check-Out” status which makes perfect sense, but for is_cancelled = 1 there are also a few on “Check-Out”.

Dataset error? Or is this a part of the case?

@andeei

When encountering this kind of irregularities, my suggestion is to make your own assumptions and record your findings in the report. Excellent opportunity to tell the employeer, client, boss that there are recording problems with the data. There is no perfect dataset in the real world!!

I hope this helps

Hi everyone, this is an entry submitted by Fred Bevan via email.

Here’s how Fred Bevan described it:

To help with the time analysis, I generated a separate table containing a separate row for each date of each reservation. This made it much easier to answer questions.

Hi @FredBevan,
I have also followed the approach of generating a record for the day of stay and basing the time calculations on the date of the stay instead of taking only the arrival date of the reservation, since, as you say, it facilitates temporal analysis, although increases the size of the dataset.
I don’t know what the rest of the participants think.

Hi @FPastor,
I wanted to consult some doubts that I have about the calculation of income and how to apply discounts by market segment and the subject of meal.

To calculate room revenue I am multiplying the AVG Daily Rate by the Total Number of Nights.
Are market segment discounts applied to these room revenues to arrive at net revenue?

To calculate the income for the meal, are the number of adults + number of children multiplied by the daily rate according to the accommodation regimen and by the number of nights? Are discounts applied to this calculation?

Regards,

@jafernandezpuga

There is not direction on this, so make your own assumptions. I will take AVG - Discount as fixed subtotal and add any other service to this subtotal to reach a total. Prices are per Room and not number of guests.

Again, my last time in a Hotel was pre-covid :frowning:

I hope this helps,

Federico
PS. Now that you’re Enterprise DNA Certifified. You only have 1 question per challenge :slight_smile:

Data can be filtered by calendar year, quarter, month or week. In this project, I learned how to insert a new table using DAX. However, due to the space limitation, I had to use the country abbreviations instead
