I am not familiar with the \"Park Royal Los Tules \" but if you mean the Los Tules in the
hotel zone next to Fiesta Americana you have booked a gem. These are condo style rooms and vary accordingly . The location is prime. The beach is the best in the hotel zone and has been for years . Gigante plaza is right across the street for any supplies you need.
An added bonus is the proximity to Fiesta Americana . The 2 resorts are joined . You can easily use the facilities of FA . The pool certainly , the weight room for $4 US just fake a room # if they ask. Much cheaper then working out elsewhere. Good gym with 7 cybex stations , free weights(50lbs max dumbells, 250 lbs freeweights) and 5 different cardio machines and a smith machine .
You have made a very good choice . Enjoy your vacation and remember us with a trip report .
