Sukkahs in the Clouds

The Gemara in Sukkah says a sukkah must be a temporary dwelling, which is why its s'chach can't sit higher than twenty amos. A few pages later it says to live in it just like your house, best dishes and furniture included. Which is it? And why does Rabbi Akiva say the sukkah recalls plain huts in the midbar, the kind any traveler would build, while Rabbi Eliezer says it recalls the Ananei HaKavod?A man saves for five years to stay in a luxury hotel, and the room he is shown into has no windows. It speaks to anyone who worries about what their hard work will bring.
