Discounted with a Paris Museum Pass. Purchasing a Paris Museum Pass (available for 2, 4 or 6 days) will provide entrance to most national museums and monuments, including the Palace at Versailles and Louvre. If you are a history and art buff, the pass will easily pay for itself if you plan your visits in advance.
The word conceived means created or spawned, although the noun form, concept, often has the connotation of an idea in some early stage of development. Biologically, it is the formation of a new offspring cell from a fertilized egg cell.
Of course, you could simply say he is going for a holiday with his children. Woud you write or say the word offspring instead of children? (Your finger may have just skipped an L on the word, but the first word should be Would.) I personally wouldn't use the word offspring in that sentence.
