Word meaning "to create unrealistic expectations"?

I'm drafting a letter to my family to announce the date and location of my destination wedding. I'm asking my family to not tell others about the wedding for now:

We would appreciate your help in not sharing this information with others, including but not limited to extended family and family friends, so as not to _.

Originally I wanted to use the word offend but that doesn't seem right - the act of telling someone about a wedding is not offensive. Disappoint doesn't really work either for the same reason.

I'd like to use set unrealistic expectations as this truly captures the intent in me asking my family not to tell others about the wedding, but this seems very wordy. Is there a word that captures the meaning I'm trying to convey?

Solution 1:

One should be careful never to overpromise because it creates the risk that you'll underdeliver.
