Google-vertalingYes they have bed rails available. We have stayed a few times at GF and it is awesome. And the pools are heated.

Google-vertalingYes both, Epcot and Magic kingdom is with the monorail and Hollywood studios with shuttle bus . The stop is right by the hotel. It’s very convenient.

Google-vertalingThe boat dock is near Narcoosies restaurant. Pls take a look at the map of the buildings and choose one that is the closest to that restaurant (the boat dock is slightly to the left. I hope this helps. If you stay in one of the outer buildings, request a lagoon view as there is a wonderful “lighted” water parade of magical boats! Happy travels!

Google-vertalingBeing in an outer building, it should be quieter. Ask what the view is, if it isn't included in your description. We had a lagoon view room on the 4th floor and were able to watch the fireworks.

Google-vertalingIt depends on what type of accommodation you booked I.e. did you book a room with views of the pool, courtyard or lagoon. The noise should not be a problem. There is transport to MK by boat or monorail. There are also free shuttle buses to all the parks. I hope this helps.
