Translation of whirlwind in German

Hans was not in the office for 4 days. I informed him that it is urgent and asked him to send it by tomorrow morning. I'll do my best that you receive it as early as possible. Trust me on that.
Let me summarize our meeting from Sunday, please give me feedback if something is unclear. I will send you the study material, including lessons and vocabulary lists to ensure the accuracy of training.
On the way back I visited a private beach resort. I just wanted to see whether I could get in and it was not a problem at all. The resort belonged to some club on the main land near Cancun.
