Spa - tickets

[audi321]

Hi all, I'm looking at taking the family to Spa next year.

Looking at the tickets, it's going to be the Bronze (I guess General Admission) tickets that I'm going to be getting.

Are these ok? Specifically for 8 & 10 year olds?

Also, will be driving in probably, so are the on site £15/day tickets the best ones?

Finally, any recommendations for accommodation?

Thanks for any advice!
