I love Hampton Court too - it's the only 'Big' show I make the effort to visit. The only slight drawback is that it is on a large site and so it can be tiring and tough on the feet if you try to do absolutely everything - especially if it's hot (Monday is forecast to be lovely - don't think I'd fancy Tuesday or Wednesday much).
If you have tickets for Monty (and you like him, obviously...) I would make time for his talk. You might welcome the chance to just sit down - perhaps Pimms in hand - and be entertained. I went to the same talk as Chicky (different location) - he was charming, informative, humorous and self-deprecating - the audience loved him.
Other than that, I would cherry-pick a few show gardens that appeal to you (more if you are going for design inspiration) and make sure there's lots of time for the floral marquee(s) if you are more into individual plants.
Whatever you do - enjoy!!
