[$10k or less] What features are necessary/nice for a wedding with overseas family?

Hi! I'm looking to have a wedding where some of the family will be coming from overseas to attend. I probably need to pay for their hotel rooms (I think?), and I'm wondering what else is.. polite.. to have? For example, is cake and punch for food too little, considering they'd need to eat real food *somewhere* that day? Should I have a welcome and/or farewell dinner? Other considerations?

Thanks!
