lol, no you're not alone on this; it is your honeymoon afterall!! So, I'm guessing you're not able to switch resorts for your honeymoon then (just in case)??
You may get a couple of people who stick around, but honestly, the week leading up to our wedding our group met up now and then but for the most part, everyone did their own thing. Maybe you'll bump into them more on a small resort, but it's they're vacation too - they probably don't want to spend every waking moment with you either (no offense! lol).
Anyways, keep on pushing those 3-night packages, I guess that's pretty much the most you can do!!
