My oldest son is the REALLY really affectionate one, and my youngest can't stand anyone touching him (outside of me and the hubby) so I quite familiar with both.
For my oldest I always felt weird telling him he can't hug, can't kiss etc, but I noticed how many other kids, including his own bro, just need their space. So at about 2 yrs I basically stopped him and explain others need their space and redirected to a high five or blowing a kiss--it really hasn't kicked in until now (3.5 yrs) to where it he does it on his own, but a quick reminder when he was younger would always work. I would just interject for the other parent and just explain your daughter likes 'high fives' or 'blown kisses' or whatever you think would be okay with your daughter.
If that doesn't work, and what I often have to do with my youngest when brother gets overly affectionate, is I just go pick him up, tell him that 'brother just wants to give you 'loves' its okay to not want it, but let's not hit'...So 9 times out of 10 he will come running to me (screaming 1/2 the time) when someones invading his personal space, but at least he's not hitting or biting :)
Good luck its a hard one, especially when so many other adults keep encouraging my oldest to be affectionate. I always have to interject that I know they're okay with it, but we're working on his 'personal space' issues, since not everyone likes it, most importantly his own brother :)
