The answer depends upon which scholarships you receive.
The AIDS 2016 scholarship program will support recipients to attend the main conference (18-22 July), meaning that accommodation and per diem (if awarded) will only cover the week of the conference (accommodation from Sunday to Saturday and per diem from Monday to Friday). This would mean that the recipient has to provide accommodation and meals while attending the pre-conference on the Saturday, 16 July and Sunday 17 July.
If awarded the flight scholarship, flight dates can be flexible in their arrangement, but the recipients are responsible for any accommodation and expenses outside of the days of the official AIDS 2016 conference as stated above. If awarded registration, scholarship recipients will have the ability to register online for selected pre-conference meetings in advance of the conference.
