meaning of phrases

i have difficulties in understanding these phrases:

refurbished amusement

implied promise

patio party

and the difference between tourguide and courier


refurbished amusement; a ride or game which has been renovated/repaired and made to look new.

implied promise - If you imply (implied) something you strongly suggest the truth of something not expressly stated. (So the promise is not directly stated)

patio party - presumably a party that takes place largely on someone’s patio, like a barbecue.

tour-guide and courier are probably often interchangeable within the same context of vacations/holidays. But a courier can also be a messenger who transports goods or documents.
