Give me some ideas on where to travel for good sun and beaches.

There are several places around the world that you could visit for good exposure of the sun and to enjoy the sandy beaches, for example:
1- Egypt, well known for sunny days most of the days, and good sandy beaches in Hurghada and North Coast of Egypt.
2- Dubai, also known for the good sandy beach and sunny days, however it might get very hot at times especially in summer.
3- Barcelona in Spain is also very good option, that you might like
