'Hope' is more natural here. 'Spent' is the past participle of 'to spend'. To use the future tense, you use pronoun + will + verb in the infinitive (in this case 'spend'). 'cause' is the informal version of 'because' so you would only say 'cause' in spoken English, rather than written. And it is written like 'coz'.
