If I understood your question correctly brother / sister, you're saying that what comes after Jannah, and can you get Greece and skiing in Jannah. 2 questions basically.
First off, the Physics of this universe doesn't work like it is in the afterlife. That's one main point. Physics of this world says that the universe will end, it had a beginning, time had a beginning and will have an end and so on; but the Physics of the Akhira or afterlife is different.
Like Allah says in the Quran in Surah Ikhlas, chapter number 112, verse number 3, He begets not, nor was He begotten, indicating that Allah doesn't have a beginning, nor an end. So we understand that time is only applicable in our universe and time was created for the ease of people, there's nothing really like time. If you do a bit of research on Time and Physics, this will be clear to you. Hence Jannah, will be forever, and forever means forever, because there's nothing like past, present and future. Everything is in a moment of NOW, or what we say, PRESENT. Either way, that's deep science and I won't go there.
Second question was you like Greece and skiing, Allah says that you will get stuff better than what you can even imagine. You will get something the eyes have never seen, the ears have never heard, the brain has never imagined, similar stuff, extraordinary. So yes you will get much better than Greece and skiing if you go to Jannah.
Hope this answers your question.
