surprise honeymoon for my wife who never got one

My wife is a military veteran who always gives more to others than herself  we got married in a courthouse near fort Campbell when she was active duty but we could not afford a honeymoon or a big weeding. this May will be our 4 year anniversary and she still has not had the opportunity to go on one. my hopes is to be able to take her on a trip of lifetime and surprise her with a proposal on one knee to renew our vows. she has no idea i am doing this on here. she is a very loving mom and wife who due to an injury overseas and being diagnosed with crones was no longer able to continue her carreer in the military. She does everything for myself and our daughter while jugling school and id like to show her that she is everything to me  any help at all will be very much appreciated thanks for your time.
