I’m torn between 4 Rius in the area, I prefer adults only but I want recommendations on the others listed below.

Las Americans - small beach, nice gentle water, I’ve heard good service, adults only, however, it appears to be very dated.

Peninsula- Adults only Villa section, private adults pool, massive resort, two beach areas, dated but not as dated as Las Americans, kids on the resort.

Costa Mujeres - fully child friendly, newer, nice area with a good beach but far from hotel

Latino - a classic Riu, very cheap (under $1000 for 4 nights), adults only, same beach as Costa Mujeres.

Any recommendations or advice would be appreciated.
