Answer
YES
Work Step by Step
Using $A=P\left( 1+\dfrac{r}{n} \right)^{nt}$ or the compound interest formula, then
\begin{array}{l}\require{cancel}
A=800\left( 1+\dfrac{0.055}{2} \right)^{2(3)}
\\\\
A=800\left( 1.0275 \right)^{6}
\\\\
A=941.4146888074142578125
.\end{array}
Since there are $5$ people each earning this much in $3$ years, then the total amount is
\begin{array}{l}\require{cancel}
5(941.4146888074142578125)
\\\\=
4707.0734440370712890625
\\\\\approx
4707.07
.\end{array}
Since $\$4,707.07$ is greater than $\$4500,$ then they will have enough to spend for Disneyland.
