Hilton HHonors - Reward room for 3 in Budapest

I am trying to book a reward room for 3 people in Budapest at either one of the Hiltons, but when it is telling me that there is no room available with those options.
Is it possible to book a reward room for 3? Do I have to call instead of making the reservation online?

It does never allow you to make a reward reservation for three people.

I would suggest you call the hotel ahead and ask if you can make a booking for two and pay-up for a rollaway bed.

A few years ago I arranged for an award stay at the Castle Hill Hilton for my family of 4 through the Diamond desk and they found us a room with 2 double beds. It wound up being on the 3 rd floor almost right above the main entrance overlooking the square. i was tole when we arrived that none of the rooms with a river view offered that bed configuration.

I've made quite a few award reservations for 3 through the DD, but only in the US. In fact, I have one coming up this weekend. It isn't hard at a Hampton or Embassy (HSV ES next Sunday night) as there are plenty of double double rooms.
