Yes, both my stays with a "food rush" in the Lounge were on weekends.

If you are going to Guam, iinstall the Stroll app. The local version of Uber/Lyft. 22 USD airport to the Westin, and no need to carry cash for the taxis.

That is definitely helpful since I always felt gouged by the local taxis for such a short distance between the Westin and the Airport.

I’ve stayed here a few times during layovers and was upgraded to the executive suite with club access each time. The rooms are quite dated and could use some renovations. However, at around 20,000~25,000 points per night, it’s a great deal for transiting through Guam, especially since it’s the only Marriott option available.

I love the hotel. Ok the rooms are dated but the loungefood is great und elitebreakfast is full breakfast at the restaurant.
Taxi was 30US one way incl. tip.
