Just Gave Up My Shower- long

A little backround: I have 3 younger sisters, I will be 40 years old in June, readying for my second marriage but it's my first wedding. My youngest sister (R) is 17 years younger than me and was originally thinking of getting married in March of 2006. Because they are young and just starting out and her FH is still in school they have decided to take a cruise to Nassau Island and elope there instead of having a wedding they cannot afford. Unfortunately, the only time they can both get a week off from work and school is the week of Sept. 5th, two weeks before my wedding! R asked for my blessing first before announcing it to the family since it was so close, she doesn't want to take anything away from me. Of course I gave it to her, I want her to do what makes her happy.
I just spoke to my other sister (G) who was trying to see if we could arrange to surprise our R and show up in Nassau for her wedding, but unfortunately, none of us will be able to afford to go - especially with it being so close to my wedding (and I go to school at night and it's almost impossible to get a night off). So I told my G that we should do something for her, so let's throw her a shower. So as not to be a financial burden on my family, I told G that if she was planning a shower for me, she should scratch it (I'm pretty sure she was planning one for me, she had insisted that I start a registry).
I am a little sad about not having a shower, but I don't want my family to know that - so that's why I'm letting it out here because you girls are great, very supportive and understanding. I am happy for my sister though and she needs household stuff more than I do.
Sorry this is so long!
