i am a spg plat marriott plat and i only need 1 more year of plat for lifetime and i have a 5 night stay half work half pleasure all paid for out of my pocket coming up in van and it is either the marriott pinnacle or here.

marriott kitchen 0700-1000 every day only, westin bayshore seems to be breakfast and dinner service every day with the coffee shop having breakfast service on the weekends in addition.

which place has better platinum breakfast? better gym? what to expect indicates no plat cocktail hour so i guess that's the case? how are upgrade chances for plat on a 5 night non-prepaid cash stay thu-tue during these rona days?
