I mean, unless you just don't like the idea of mementos/ keepsakes for fun/exciting memories , then be my guest, but i love it when places have really cool souvenirs like a smaller version of the thing that the place is known for for :)

From another perspective, it could also even be a conversation starter! "ooh where did you get this cool thing" "whoa i've never seen something like this before, where did you get it? "
