My 32nd Birthday

I will be 32 in september and am looking for a theme that will best fit me. I`m looking into something like, "32 and loving it!"
Anyway, since I totally forgot to celebrate my 30th birthday I thought I`d make a luau or sorta bash at my tennis club to make up for it.
The thing is too, I have 2 kids now ( one is 4 months and the other is 4-years-old) and I would`nt want to exclude them from attending my party.
How could I also make it so that it also involves my invitees plus their kids?
¿Any tips?
Thanks,
Isabel.
