I know subjunctive is very hard and that people are taught
Espero QUE disculpes ......................
When I answered a Spanishdict member I omitted the QUE and wrote "espero disculpes..........." without QUE . He kindly called my attention to this and I couldn't answer what had happened. The only thing I knew was that it sounded natural to me without any explanation. The above address could give some ideas about it. Of course it's very advanced grammar but maybe Daniela or some of the others who know Spanish grammar could get some ideas from it and maybe explain if the absence of QUE could be right. I really don't want to mislead anybody.

Ruben Fuentes, from Gusmán, Jalisco, wrote the song "La Bikina" in the mid 1960s with one verse "No permite la quieran consolar", so appearantly omitting the que was done back then, but I always thought it was simply to fit this one verse into a measure of music and I never heard this type of sentence structure ever again.
Even if there is some hidden grammer rule allowing this, it´s certainly very uncommon to speak this way, although it may be a regionalism.
Espero "que" + subjunctive is considered "proper" However, "Espero without "que" is becoming quite popular.
It is similar to "Juego al baloncesto." This is what is taught in ALL the textbooks, but ALL of my native speaker Spanish students omit "al". It may be a Mexican thing. All my native speakers are either Mexicans, or Californians of Mexican descent.
Según la R.A.E.
Cuando significa tener esperanza [en que algo suceda] o creer que sucederá, es transitivo y va seguido de un infinitivo o de una oración introducida por que: «Espero llegar a vieja sin arrugas» (Allende Eva [Chile 1987]); «Espero que todo te vaya bien» (Gala Invitados [Esp. 2002]
Here is what Butt & Benjamin say in A New Reference Grammar of Modern Spanish (2011)
23.4.6 Omission of conjunction que
Que is occasionally omitted, but much less often that the English 'that'
(a) if the following verb is in the subjunctive, and especially with the verb rogar que (to request). This construction is practically confined to business letters and other official language, but it it also found in sub-standard language. Foreigners should probably avoid it.
Then they have three example sentences which begin (1) Les ruego envién..., (2) No importa le tilden de bufón and (3) Solicitan se les solucione la deuda que ....
(b) In relative clauses introduced by que so as to avoid excessive use of que. This is probably confined to written language.
Just passing on what I read. I have almost no personal experience with the topic.
