I am also spending Easter alone (widowed just over 2 years ago and have no children). It is hard when families and couples are celebrating or just enjoying a holiday, I wish I could say it gets easier but for me it doesn't. I try to keep busy - with the lovely weather we are having at the moment I have been out for long walks, but if the weather is bad I will do one of those jobs that I keep putting off! Of course there is always GN - there is usually someone on here to "talk" to.
Someone told me that grieving is not a process, its a cycle - so it comes round again, for you this year you are also missing your children - so be kind to yourself, if you feel like having a little weep then go ahead (I know I do), then start remembering the good times. 
On a practical note, try not to worry about your children travelling - flying is one of the safest ways to travel these days and they will be back before you know it full of stories about the holiday and eager to show you the photos.
