Help with reward flight

Hi all,
Me and the better half are booked onto VS01 for our first ever upper class trip (thanks to v-flyers for all the tips). However, we fly in April so unforunately our departure time has changed to 09.45 which severely limits our chance to fully enjoy the clubhouse experience :0 . I will call VS to see if I have any options but thought I'd ask here. Can reward flights be changed? assuming there is availability on another flight. Looking at the times now, we would like to get on VS09,17 or 25. We will be staying at EWR(or JFK should we get a change)the first night so early arrival isn't really an issue, Clubhouse time would be much more appreciated during the afternoon i feel
.
Either way, we will be able to guest someone into the clubhouse on the 10/4/14...just not sure what flight we'll be on yet.
Thanks for any help and for all tips and info I've picked up lurking on here over the years.
