kids going as adults

When I was booking my family holiday, for 2 adults and 2 kids, the travel agent told me it was cheaper to put the kids on as adults, we done this, but are now worried that this may cause problems, either at the airport, or hotel.
Can anyone tell me, if this is okay to do.

I assume this was a package holiday in which case it makes no difference if children are put down as adults, (as opposed to putting down adults as childfen which can make a difference for some hotels).

Having worked for hotels and airlines and tour operators before becoming a travel agent I am sure you're O.K. I do it loads of times if the passengers get a better deal that way.
But make sure you have accurate ages for insurance company.

Thanks, yeah the correct ages are in for the Travel Insurance, as I tok out my insurance seperately.
Double checked with Travel Agent today, and they told me the same, that it would be different, if you tried to book an adult, ina child place.
