Rydym hefyd wedi buddsoddi mewn seilwaith, er enghraifft, yn Abergwaun drwy'r Cynllun Cymorth Buddsoddi mewn Twristiaeth, rydym wedi buddsoddi mewn pont gychod er mwyn caniatáu i longau mwy o faint ymweld â Chymru. O ganlyniad i hynny, rydym eisoes yn gweld cynnydd o 30% yn nifer y teithwyr ar gyfer 2019, gan gynnwys ymweliad gan y llong fordeithio Aidabella, sy'n cario 2,500 o deithwyr. Hon fydd y llong fwyaf i ymweld â Chymru hyd yma.
We have also invested in infrastructure, for example in Fishguard port through the Tourism Investment Support Scheme, we have invested in a pontoon allowing larger cruise vessels to call.  As a result, there is already an increase in passenger numbers for 2019 of 30%, including the arrival of the Aidabella cruise ship, with 2500 cruise passengers on board. This will be the largest ship to call in Fishguard so far.
