There are a few normal things to keep in mind if you are looking at a large number of tunnels, such as each tunnel interface requires an IDB so with a large number of tunnels you might possibly have an issue with IDB limits (but since these limits are pretty high - and vary by platform and by release - I do not think this is likely to be a problem). If you are going to run a dynamic routing protocol over the tunnels you may need to think about how many neighbors the router will need to maintain. And some things like that. But in general there are not any particular problems with running many tunnels.
How many tunnels are you talking about when you say a large number of tunnels? I have a couple of routers running over 200 tunnels and have seen no problems with it.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
