Honeymoon guilt should I feel it?

We have booked our honeymoon for after our wedding in October next year. Now we have 5 children who will be staying with grandparents while we are away. Now I know how lucky I am to have someone to watch them while we get to enjoy a week away abroad. But I feel so guilty about it, having a lovely holiday without them. Don't get me wrong I can't wait lol but did anyone else experience this? And should I feel so guilty? xx
