My last Vegas trip had a $45 daily resort fee that wasn't clear upfront. I learned that even when you call, some front desk agents might not mention all the extra costs. It's worth digging through online reviews on sites like TripAdvisor where people list out the real charges. I always add 30% to the listed room rate now to cover taxes and fees, which keeps my budget on track. Honestly, it feels like a game where they hide the ball, but you can win by being super careful.
