Myra the magnificent interaction question

hey i had a question about the order of how spells "attached" to attractions get cast. lets say i have 4 attraction open with spells "attached" to them. one of these attractions is haunted house. if i choose to have haunted house visit trigger happen first does that creature enter the battlefield before my spells from the attractions get cast? would i be able to bring back a guttersnipe and it trigger from the spells cast from the attraction that turn? basically when i roll to visit the attraction are all spell casting triggered as the roll resolves or do i transition from visiting to casting? sorry if this is confusing. thank you for your time!
