Naha hotel translation please

Can anyone translate the 2 sentences below for me please? Thanks a lot in advance!

I will arrive at Naha airport at 19.45. I guess I will be at the hotel between 21.00 and 22.00 hours, please keep my reservation. Thank you.

No need translation just pretty basic english.
All Hotel staff can read such simple reply no worry.

But don't forget to add
- reserved date/check in time(if booked)
- yr name
- cellphone numbers (if u have)

As Mer said, they can read it, I think too.

I will arrive at Naha airport at 19.45.
19:45に那覇空港に到着する予定です。
I guess I will be at the hotel between 21.00 and 22.00 hours
ホテルには21時から22時までの間に到着できるだろうと思います。
, please keep my reservation.
予約は取り消さずそのままにしてください。
Thank you.
よろしくおねがいします。

Thanks, Mer & Ajapaneseboy. I know I'm tiresome ;), but could you translate these short sentences for me as well?

I booked a room in your hotel (24-26 August), but I have one question: is there a yukata provided for going from the room to the showers and back? I'd like to know this, so I know what to pack in my suitcase. Thanks you for answering me.

Yours truly,

How about this.

こちらから持参すべきかどうか決めかねておりますので、
Thanks you for answering me.
ご返答いただければ幸いです。

Thanks a bunch, Ajapaneseboy, you're great!

Oh, you said you're tiresome?!

No, you're very respectful and careful.
I just said that hotel staffs especially in Okinawa can read easy English.
Have a good stay!

I meant I kept asking and asking for a trranslation.
