Not necessarily.
The 300dpi is their highest print resolution, but they can probably make it bigger(lower resolution).
The quality of the print depends on how closely it will be viewed.
For example, I recently had a poster printed for work, the poster was 2.4 x 2.4 metres and done at a print resolution of approx 50dpi(approx two pixels per millimetre). The poster was on display at the back wall of a trade stand at a conference and approx 3 metres away from passers-by. At this distance the 'pixels' were not noticable.
