"Does anyone know if it can be used at more than one location on the same day?"

Yes - you can use as many 2for1 vouchers as you can squeeze in.

" If there are children 10 and younger who ride free, would their parents be able to get 2 for 1 using the adult tickets?"

Sure.

Agree with janisj - would add that you need to print out separate tickets for each deal you want to take advantage of, so just make sure you do that and you should have no problem.

jamikins...you mean separate COUPONS, right, not separate tickets.

caer...be sure to print out coupons for any attraction for which you even suspect you might visit...better safe than sorry.

jamikins...my characterization was wrong, too - they're called vouchers I believe.

You print separate coupons (vouchers) for each attraction, and you turn them in when you enter and pay. You'd only need duplicates if you planned on visiting an attraction twice...or if you had four adults...which is permissble.

You never turn in the Travelcard...you just show it...so, obviously, you can use it as often as you wish, provided you have the necessary vouchers printed.

[We've used the vouchers on our last four visits to London -- with both train tickets and Travelcards. We print out the vouchers before we leave the US...have saved over $100 per trip on average.]
