On May 1 (in 2 weeks), I'll be moving to another apartment in the same complex (we didn't know ahead of time this would be our plan, but a bigger apartment opened up, so FI and I decided that I should go ahead and get it before it was taken by someone else). We sent out the invites this past weekend - some were hand-delivered and some mailed, but we were still stuffing envelopes and writing addresses the same day that we decided on the new apartment, so we had time to change the return address.
I had already ordered labels to use for the return address on the RSVP's and fortunately, my new address is exactly the same except the apartment number is one digit different. So, I decided to go ahead and write over the old number with the new number. It actually didn't look too bad, since only one digit changed.
However, I realize that there is a 2 week gap and I'm wondering if the USPS will deliver the RSVP's to my new address before I actually make the move. My name will not be on that mailbox, so I'm worried they might not deliver them. However, there won't be any return address for the person who mailed it.
So . . . the RSVP's might go to the new mailbox, which I can access as of May 1, or they might just go to my current mailbox b/c it currently has my name on it, or they might disappear into lala land. My mom suggested that I tape one of the return labels on the new mailbox to give the postal worker a heads-up that this really is my mailbox (or at least, it will be very soon). I also put in a forwarding address starting on May 1.
Originally, I thought I would just leave the old address on the envelopes and do the fowarding thing, but I assumed most people would probably wait until a few weeks to mail it back anyway, so I might as well just put the new address so I don't have to wait for them to be forwarded. I also wanted people to have my current address.
IDK if I did the right thing, but it's already a done-deal, so I guess all I can do now is wait and see what happens

. So I guess my question is, do you think I did the right thing? If not, can I still fix it?
ETA: Not a significant part of this issue, but to clarify, FI and I live separately and I'll be moving first into the new apt, then he'll join me when we're married. I did NOT want the RSVP's sent to his address b/c his mom also lives there and she has been a bit crazy with wedding stuff, so I wanted all the RSVP's sent to me, since I'm hosting and planning everything.
