30th Wedding Anniversary

Our 30th wedding anniversary is in 3 weeks. We never had a 25th celebration (caring for elderly parents at the time). (I planned a stressfull 3 day Niagra Falls week-end for my husband and I- hecouldn`t believe I hadn`t planned something for our 25th. Although I was working full time and caring for his 2 parents and my 2 parents (all ill) in our home. Felt guilty so planned the Niagra falls thing under duress. We have 3 adult kids 25,27 & 28 and have helped them all with their homes etc. What role does etiquette play in planning a 30th for us? I have planned everyones parties and truly don`t have the gumption to plan another for us. Should we just do without, grin and bear it without any memories? I will be lucky to get a card from any one except for my sweet Aunt who has never forgotten an occasion. Thank you. My husband has 2 sisters, 2 brothers ( all in our wedding) I am only child but have friends/close cousins etc. Thanks, again.
