72h weekend in Maspalomas, car or bus?

Hello, we booked an apartment near the Maspalomas dunes from December 7 to 10, Thursday to Sunday, for the first time in GC. There is no possibility of private parking. We are a little perplexed about parking, insurance, foreign regulations , traffic and we are usually not used to booking a car during the holidays (I drive but I'm not very smart about renting). We are excellent walkers (10-15 km per day). But we are also concerned about the fact that during the holidays there are fewer buses. 3 days in Maspalomas may be enough (or not), but we would also like to visit the North, at least Agaete and LasPalmas. We would like to include Agüimes, Arucas and Puerto de Mogán, but only the latter is easily accessible in bus.Then the question is: rent a car at the airport, or do the entire trip by bus, or do half? Or stay 72 hours in Maspalomas, that's all (and maybe buy there one day trip of the Island)? Any comments and suggestions are very welcome.
