Could you please check this letter, please? Thank you.

1)I'm still looking for an accommodation in Yellowstone Park but everything is sold out from 8 to 12 August.

2)My husband booked a cabin in Old Faithful lodge last week under the name "Grande" and sent you details of his credit card. However, we haven't received a confirmation of our booking, yet.
Could you please let us know about it as soon as possible?

Both are phrased just fine! =)
