happy to

[navi tasan]

Consider:
1-I am happy to visit Paris.
2-I am happy to be visiting Paris.

In which case:
a-I am in Paris
b-I am going to go to Paris
c-both are possible

The speaker of the second sentence is definitely in Paris (a). The speaker of the first sentence might be in Paris, but he also might not be (c). (The second sentence is, I think, more natural.)

2 sounds as if the person is there, and would be the form if that is the case, but it could also be used to indicate a future arrangement, if the tickets have been bought. ;-)

 

[RonBee]

If you had bought the tickets and were headed there wouldn't you say I am happy to be going to Paris?

To use the present continuous, you' have to add a time phrase:
I'm happy to be visiting Paris next month. ;-)
