When I told my daycare parents at about 12 weeks, the reactions were mixed...some were incredibly excited and supportive and others felt I should have told them immediately (which I thought I did!). I too will only be closing the daycare for two weeks-and will have my husband to help for a bit as he will be taking a short parental leave. What I have learned is that there is nothing you can do-parents are going to do whatever they feel is best for them. I do think it is best to know your plan, but even then be prepared that some families may withdraw their child from care. Best thing to do is just be honest and upfront...this is after all a lovely time for you and your family, congratulations!
