Ambassador Transit Hotel T3

[Kiwi Mile]

If one isn't a transit pax, is there any way I can still book a room and use it after checking-in? The website states I have to provide an arrival flight info in order to confirm the booking. I have to spend some time in the city earlier in the day where the heat & humidity is likely to wear me down so I would like to get in there around 18:00 to shower and rest in bed before the 23:55 departure & 14-hour red-eye to CDG in the back.

FYI I will be staying at the Swissotel Merchant Court the night before.

Book it without the flight details but ETA. I never had problem booking room last 10 years. My last stay was Jan 14.
