I love love love wrapping gifts and doing funky techniques with paper and ribbon, I'd be really sad if I couldn't do something super fun for a good friend or family member.
I'm not big on the "OMG its MY day and forget everyone else's feelings" stuff, but seriously, it is about you at least a little bit LOL especially at the bridal shower. If you want a dry shower, do it! If you want a signature cocktail, do it! If you want wrapped presents, do it (I would). No need to justify your choices if your gracious and grateful to your guests! Which you sound like you are, you seem very normal, I didn't mean to insinuate otherwise LOL
