family is going over board with my babyshower..

I've planned my own shower not asking for help I was planning on something small because that's what I could afford... but since my family knows I'm on my own they've bought their own things or pitched in for something... for ex. someone is paying for food, someone else is in charge of the candy table, a cousin for the cake.. but it's become a bigger event than I had hoped for because I'll be 36 weeks and I didn't want to deal with a lot of people.. I'm grateful for all that they're doing but they're all inviting their own people who i don't even know.. I don't know if I should tell them something since they are putting money into it
