Well I think you should test the porosity of the stone-just puddle up a palm sized puddle of water and let it sit.Wipe it away after 10 minutes or so and you will see most likely that the stone hasn't absorbed anything.(sometimes they can be absorbent but light travs are generally pretty dense)
This way you can see how much sealer will be needed or used. Most times with travertine you wont need much.
Darker travertine can be more porous than the lighter ones.
So the key for you to keep the job simple with an easy cleanup is to make sure what ever product you use must be completely removed from the surface.
This way your outta there in time without any epic adventures and or callbacks.Let your customer know your are sealing with a high quality product and they can sleep well knowing their new stone is sealed.
A side note-you should tell them that the sealer is impregnating and will protect from the intrusion of staining agents and make future cleaning "easier". I would tell them the rough surface of the travertine(looks like a thomases english muffin under a microscope) is what attracts and holds surface soils along with the change of seasons and possible pooling of water in areas.

Thanks Stu,
The floor is only 1.5 yrs new.  He wants it sealed.  I do have the SCC solvent sealer, but I am trying to move older stock.  Is the water-based sealer good enough in an outdoor setting?

Agree with fred-most lighter travertines  wont take much sealer so the color enhancer generally doesnt have much of an effect.
If you need to turn around the stock you could always use it sparingly and make sure you clean 100% of the residue off.
It will darken the grout lines if they have them.
I think that product is formulated for more porous stones.
Dont think I would recommend a water based sealer-but if you have it to use why not charge and apply.
Any stains in the surface now ? How many years old is the install?That may help you make the decision but if your customer wants it sealed and pays you have product on hand!!

It will fade for sure. as far as it being blotchy, it very well maybe since a lot of travertine is very dense.

Hi Partners,
I am going to be cleaning and sealing a half covered outside porch made with light colored travertine tiles.  I have a ton of SCC color enhancing sealer and because this is an outside project (not worried about the odor) I would love to use some of my stash up.  I am worried about the stone sucking up the sealer in an irregular way and looking blotchy later.  I am concerned about the sunny side of the porch fading more than the shady side.  I can test a small are to see how much darker it will make the stone. 
Also, would anyone recommend the SCC water-based sealer.  I have a few gallons of that too!
Thanks,
Barry
