まだチェックインはしてませんって英語でなんて言うの？

If you have not done something but will do it shortly, then you may use the phrase: "I have yet to' + Verb. Eg. "I have yet to speak to the client."

I still need to check-in first before I can tell you my room number. After I check in, I can tell you my room number. Here are two additional ways to express yourself when needed to inform someone that you are required to check in before providing the room number. With each example, you are simply letting the person know that you need to check in before you can provide any information about your room. I hope that these examples prove to be useful to you.

These expressions are expressing that you have not 'checked in', this is the term used when at a hotel and you speak to the receptionists/staff and notify them that you have arrived and then will be shown to your room where you will stay.

If you "have the chance" to do something, it means to be able to do so. Once you explain this to the person at the reception desk, they should either help you check you in or ask you about your reservation. I hope that this helps. :)

I am politely greeting the hotel receptionist as it would be common courtesy to do so in a formal situation in order to show my good manners and respect and asking them if they are able to look after my luggage until I am ready to check into my room. I have asked them if they can please hold my luggage and keep it safe until I am ready to check in. Using the words 'until I am ready to check in' convey the meaning that I am not yet ready to check in to my room but I wish for the receptionist to hold my luggage for me until I am ready to take it up to my room.

Both of these answers explain to a receptionist that you have not been assigned a room yet as you have not checked in. Most hotels will be able to look up your booking however and see that you have a reservation so that they can hold your bags until your check in time.

I do not have a room number, I have not checked in yet. - This is used to express that you do not have a room number. This helps the listener to understand also why you do not have a room number. The result of this expression will enable the listener to check you in to provide you with a room number. I have not yet checked in so I have not been given a room number. - This expresses the same message allowing the listener to know you have not yet checked in and but have a reservation already booked.

The expression 'I haven't checked in yet', used in the first sentence, actually means that 'up to this moment in time, I have not checked in' and the result is that I don't have a room number. The expression 'I still have to', used in the second statement means that I haven't checked in yet, but will do so later, and that is why I haven't been given a room number 'yet'. The usage of the adverb 'yet' in all three statements signifies that something, checking in or being given a room number in this case, has not been done up to this moment in time but it is going to be done later. So, you may say to the receptionist: I haven't checked in yet, so I don't have a room number. or I still have to check in, so I haven't been given a room number yet. or I don't have a room number because I haven't checked in yet.

When you want to tell a receptionist at the hotel that you have not checked in but you want them to keep your luggage; then you may say this in the following ways: -Could you please hold my luggage? I'm going to check in later -I have not checked in yet -I'm only checking in later.

I have yet to check in. - This means that you have not checked in yet but you will. Yet- still, up until now. E.g- I have not completed the project yet. I have not met the new girl yet. (I have still not met her.)
