On a different note from my last post. I wanna surprise my hubby with a low key, lower budget but fun ideas for the holiday weekend. I'm 29wks and most amusement parks are out (although Hershey park boardwalk would be nice but too much for us right now) so any ideas? We are a military couple (go Army!) so military discounts are appreciated.
