How to explain something in japanese?

Question:

I'm trying to book and pay for a capsule hotel in osaka in advance, so far i've managed to let the capsule hotel know that i want to pay for my stay in advance, a managed to get this far

" 私は事前にこの部屋の支払いしてくださいすることができます

私はクレジットカードを使用してください "

they responded with:

"Thank you for your inquiry.
Why do you prepay it?
Please teach us the reason.


Capsule Hotel "

How would i say in japanese that i'd essentially like to pay for the accommodation in advance so i won't have to worry about it upon check in its really just a matter of preference..

any help would be greatly appreciated.

Answer:

チェックインするときにお金の心配をする必要がないからです。
これは単に好みの問題ですが，私はどうしても先払いがいいのです。お願いします。
