Mountainous areas will be cold, 10-12 degrees or less, however it’s a pleasant time in Dead Sea, Aqaba, Petra and Rum

Jerash and northern historical places (Ajlon, Um Qais) will be kindda chilly

Hotels in the dead sea area (Kempinski, Moven Pick and Marriott) offer heated pools

Hotels in Aqaba (Moven Pick, Marriott and Intercontinental) also offer heated pools

All above have special kid zones and activities during Eid, but you need to start your booking, probably you will find them sold out

Enjoy the break.. there will lots of things an places to see there
