present perfect/yet/already/just

Hi

I've been trying to write a story using the present perfect tense as often as possible and also using such words like: just, already, yet.

Can you have a look at this? What would you change to make it sound better?

It has been the best holidays of my life. I have never seen so many things at one time yet. When Jerry and me have already landed in Egypt we got out of the plane and headed for our hotel. The trip has been very tiring so when I wanted to talk to Jerry in our hotel room I've noticed that he has just fallen asleep. In Egypt we have seen something that we hadn't seen before yet - beautiful monuments, magnificent views, great pyramides and loads of tourists. When we've already seen everything we have decided to move on and have flown to Dubai. The moment we got off the plane we could see all those modern and high skyscrapers, beautiful hotels, sandy beaches and reach people everywhere - something we have never seen before yet. After three days we got bored so we have bought a ticket and flown far away to Australia. Of course Australia is a great place to be and we've done a lot of sightseeing there, but unfortunately I have left my wallet at one of the restaurants. When I came back to that restaurant my wallet hasn't already been there, someone has just taken it. And it was the end of our trip. When we have just arrived home we have already started to plan the next trip to the places we haven't been yet.

thanks
