babymoon and weird looks/staring

Denise • Hey girls hey 💁
I'm currently on my babymoon with my husband (31 weeks). I was feeling pretty good about myself prior to arriving in Thailand but I notice I keep getting these looks from the other gust at the hotel. It's one of 3 looks. 
1. Someone will look at me like aww look pregnant lady with a smile. 
2.Blank face but stares hard at me/belly
3. Won't stop staring, looks disgusted. 
I just don't get it, my belly isn't THAT big, I've been told that I carry well. So what's the deal with the staring?
