Hi Jim,
Thanks for reaching out.
I would highly recommend checking out our page on
Belfast, if you scroll down you can find our 'Belfast Highlights' which has a number of attractions which may be of interest. There are free attractions like
Botanic Gardens, which will not need to be booked in advance. However, you may want to book tickets online for the likes of the
Titanic Museum or the Black Taxi Tours.
Let me know if you have any other questions and I would be glad to answer.
