Las Vegas Weddings/Renewals?

Anyone have opinions/been married/guest at a Vegas wedding or renewal? My hsband and I are thinknig about a vacation, and I'd like to plan a wedding renewal (he sprung a surprise wedding renewal on our recent cruise). I haven't had much research yet, but in the different sites, I'm drawn to the Red Rock Canyon package. Besides the intimacy of the ceremony (no guests, just me and him) we both are fans of nature type locations, pulling me towards Red Rock. But some of the other options kinda tugging me are things like one at a hotel/casino in which the ceremony is timed so that the water fountains erupt at the pronouncement of husband and wife.....or any other suggestions? We aren't doing this vacay for about a yr. so I have time to plan and prepay. Any suggestions to sites or experiences are greatly appreciated (I'm afraid to speak to the vegas wedding 'consultants' because I don't want them to draw to their location, or promise what I ask for now, and it change over time)
