People start staking out the Riverbelle Terrace about 5-5:30'ish - depending on how close to the railing they want to be.
Your other options are
* Waiting for a couple of hours on the ground in the seating section
* Waiting for 1-1.5 hours on the bridge over Pirates
* Waiting in the standing only areas about 1.1.5 hours before
* Going over by the Haunted Mansion about 45 mins-an hour before, and find a place to stand.
Be sure that you are not in a walkway, because the CMS will move you along when they need to - doesn't matter how long you've been standing there.

Maybe a person for every three in your group to save space - that's fair for those waiting while others enjoy the park.
I've done the Riverbelle Terrace a few times (as recently as last Friday), and only when we have out-of-town guests, especially those who may be older, or who need to sit in a chair instead of the ground. Since I go so often, I rather enjoy relaxing on the patio & chatting w/other guests. I usually take a book, but never get past a page because of the people watching & visiting with other people. By the time we have a leisurely dinner, a drink or two, and talk, the time doesn't seem that long for waiting for Fantasmic.
BTW - I wouldn't recommend Riverbelle Terrace for those who are visiting for a couple of days or so - their time can be better spent enjoying the park.

Also, if time allows it, I recommend seeing the 2nd show -- a lot of people can go up there and get a decent spot after the 1st show has let out.
Caution -- In between shows, it is rather chaotic, with all of the people leaving and coming in. Back in March, when we were there, the crowd was at a complete standstill, which is a nightmare for those w/small ones, or those who have problems with crowds.
If you're going to see the 2nd show --
Frontierland = entrance
Adventureland = exit
The crowds are directed that way (mostly)
Try taking the train that will let you off in New Orleans Square & then walk up to a spot to watch the show.
Disneyland Fantasmic is a spectacular show & well worth the view.
Fantasmic & Fireworks (when the fireworks are showing)
Cannot see the fireworks from Riverbelle Terrace. You need to be in the area from Pirates to Haunted Mansion.... Look for the cable that guides Tinkerbell through the trees -- if you can see that, you've got a decent spot for the fireworks after the first Fantasmic show.
