Open Neighborhood Rather than Open World

Many pople had incredibly long loading screens when switching to a sub world (holidays for example). I personally loved world adventures, but found myself using it less and less, because I had 5 minutes loading screens, so I would hope they could change that if there is a sims 5. Another huge improvement that I would hope they would do is that you can travel between worlds. They could each be open and there could only be a loading screen between worlds (short). What I did not like in sims 3 was that every time a new world came, it required a new save. I think it limited everything so much. I only play one save, so now I actually am able to use all worlds and features offered in EPs.

While I believe all the necessary changes to make an open world great could be done, I am worried that loading screens would be crazy long.
