Seats at West End

Hello! I am finally fulfilling my dream of going to watch Phantom for the first time, however, I must mention it is the first time I go to the West End like... Ever. I bought tickets for Royal Circle row B20, it was not cheap at all. I am not short (172cm tall) but I heard a few feedbacks about the view being restricted there depending on who sits in front of you. :( I am really worried. Can anyone here share your experience with this seat or with similar ones? 🩷 Is it possible for someone to be sat right in front of you and ruin the experience?
