Hi,
I will answer the Laundry question.
Holiday Resort is north of Sengiggi "downtown" or strip where you can find some laundry signs. It is about five minutes by taxi. I will share my experience.
In the apartment there are at least two towel racks that residents use on the verandah. I used this for the items I washed myself.
For my pants and shirts I used the service available there. You call the laundry number and someone will arrive with a cane basket and a receipt that you fill and check the boxes for starch, dry clean etc., and the next day it will be delivered to your room. The prices are reasonable.
WiFi is new to me. Two years ago I used to go to their airconditioned Internet room off the lobby and used one of the two desktops with cable connections. It is available 24 hours and you get the key from the Front Desk. Now things may have changed. You can google this or better call the Front Desk.
Not all at the Front Desk are familiar with Internet. There is one guy who is the trouble shooter. He is usually on duty some time during the 24 hours.
I wouldn't worry too much about this because they provide this service for guests from Europe and other countries. So they must have some standard interfaces.
Enjoy the preparations for your trip.
Josi
